Zusammenfassung
Large statically indeterminate truss and frame structures exhibit complex load-bearing behavior, and redundancy matrices are helpful for their analysis and design. Depending on the task, the full redundancy matrix or only its diagonal entries are required. The standard computation procedure has a high computational effort. Many structures fall in the category of moderately redundant, i.e., the ratio of the statical indeterminacy to the number of all load-carrying modes of all elements is less one half. This paper proposes a closed-form expression for redundancy contributions that is computationally efficient for moderately redundant systems. The expression is derived via a factorization of the redundancy matrix that is based on singular value decomposition. Several examples illustrate the behavior of the method for increasing size of systems and, where applicable, for increasing degree of statical indeterminacy.

Zusammenfassung
Redundancy matrices provide insights into the load carrying behavior of statically indeterminate structures. This information can be employed for the design and analysis of structures with regard to certain objectives, for example reliability, robustness, or adaptability. In this context, the structure is often iteratively examined with the help of slight adjustments. However, this procedure generally requires a high computational effort for the recalculation of the redundancy matrix due to the necessity of costly matrix operations. This paper addresses this problem by providing generic algebraic formulations for efficiently updating the redundancy matrix (and related matrices). The formulations include various modifications like adding, removing, and exchanging elements and are applicable to truss and frame structures. With several examples, we demonstrate the interaction between the formulas and their mechanical interpretation. Finally, a performance test for a scaleable structure is presented.

Zusammenfassung
In the present paper, theoretical foundations of redundancy in spatially continuous, elastostatic, and linear representations of structures are derived. Adopting an operator-theoretical perspective, the redundancy operator is introduced, inspired by the concept of redundancy matrices, previously described for spatially discrete representations of structures. Studying symmetry, trace, rank, and spectral properties of this operator as well as revealing the relation to the concept of statical indeterminacy, a continuum-mechanical theory of redundancy is proposed. Here, the notion “continuum-mechanical” refers to the representation being spatially continuous. Apart from the theory itself, the novel outcome is a clear concept providing information on the distribution of statical indeterminacy in space and with respect to different load carrying mechanisms. The theoretical findings are confirmed and illustrated within exemplary rod, plane beam, and plane frame structures. The additional insight into the load carrying behavior may be valuable in numerous applications, including robust design of structures, quantification of imperfection sensitivity, assessment of adaptability, as well as actuator placement and optimized control in adaptive structures.

The degree of statical indeterminacy as a fundamental property in structural mechanics is today mainly known as a property of a complete system without any information about its spatial distribution. The redundancy matrix provides information about the distribution of statical indeterminacy in the system and by this gives an additional valuable insight into the load-bearing behaviour. The derivation and definition of the redundancy matrix are presented based on truss systems and its mathematical properties and their mechanical interpretations are provided. The definition of the redundancy matrix is extended to other discrete systems like beam structures and a definition of the redundancy density is given for the continuous 1D case. Potential applications of the concept include robust design of structures, quantification of imperfection sensitivity as well as assessment of optimal actuator placement in adaptive structures.

Zusammenfassung
Taking advantage of adaptivity in the field of civil engineering is a subject of ongoing research. Integration of adaptive elements in load-bearing structures is already well-established in many other engineering fields, albeit mostly for different purposes than withstanding predominantly static loads. Initial investigations have demonstrated potential for substantial material and energy savings also in the field of civil engineering, especially for high-rise buildings and wide-span structures, such as roofs or bridges. Adaptive civil structures show promise in tackling current challenges arising from emissions and shortages of materials. In this study, we compare the possible minimum-weight designs for different actuator placement approaches and for different structural topologies that satisfy various constraints for high-rise buildings. We use case studies as illustrative examples to show which advantages and disadvantages can be expected from a specific design. The overarching aim is to learn how truss and beam structures should be designed to perform well as adaptive structures.

Zusammenfassung
The skeleton of Echinocyamus pusillus is considered as an exceptional model organism for structural strength and skeletal integrity within the echinoids as demonstrated by the absence of supportive collagenous fibres between single plates and the high preservation potential of their skeletons. The structural principles behind this remarkably stable, multi-plated, light-weight construction remain hardly explored. In this study, high-resolution X-ray micro-computed tomography, finite-element analysis and physical crushing tests are used to examine the structural mechanisms of this echinoid’s skeleton. The virtual model of E. pusillus shows that the material is heterogeneously distributed with high material accumulations in the internal buttress system and at the plate boundaries. Finite-element analysis indicates that the heterogeneous material distribution has no effect on the skeleton’s strength. This numerical approach also demonstrates that the internal buttress system is of high significance for the overall skeletal stability of this flattened echinoid. Results of the finite-element analyses with respect to the buttress importance were evaluated by physical crushing tests. These uniaxial compression experiments support the results of the simulation analysis. Additionally, the crushing tests demonstrate that organic tissues do not significantly contribute to the skeletal stability. The strength of the echinoid shell, hence, predominantly relies on the structural design.

Zusammenfassung
Adaptive structures in civil engineering are mechanical structures with the ability to modify their response to external loads. Actuators strongly affect a structure’s adaptivity and have to be placed thoughtfully in the design process to effectively compensate external loads. For constant loads, this property is introduced as steadystate disturbance compensability. This property can be linked to concepts from structural engineering such as redundancy or statical indeterminacy, thus representing an interdisciplinary approach. Based on the disturbance compensability matrix, a scalar performance metric is derived as quantitative measure of a structure’s ability to compensate the output error for arbitrary constant disturbances with a given set of actuators. By minimizing this metric, an actuator configuration is determined. The concept is applied to an example of a truss structure.

Different partitioned strong coupling approaches are presented and compared with respect to their efficiency. In addition to the classical block Gauss-Seidel iteration and a Newton-Krylov approach, a two level coupling scheme is introduced. It is based on a coarse grid predictor followed by the usual iterative fine scale solution. The performance of the three coupling schemes is investigated applying a two-dimensional model problem of a membrane roof. Three-dimensional numerical examples demonstrate the mechanical and numerical sensitivity for these especially delicate fluid-structure interaction problems.

This paper is concerned with a coupled thermo-hygro-mechanical damage model for concrete and its application to numerical simulations of long-term degradation of concrete tunnel linings. In the model, time-variant loading-, temperature- and drying-induced degradation of concrete structures as well as the various interactions between these degradation processes are considered. The formulation of damage potentials for partially saturated concrete is based upon the concept of effective plastic stresses resulting in a fully coupled theory which allows for the numerical simulation of shrinkage cracks and for the moisture-dependence of the strength and stiffness of cementitious materials. For the numerical representation of moisture transport, a macroscopic anisotropic permeability tensor is employed which considers the influence of the moisture content, of the crack width and of the temperature. The numerical model is applied to long-term analyses of tunnel linings subjected to thermal, hygral and mechanical loading. This example demonstrates the ability of the developed simulation model to provide reliable life-time-oriented prognoses of the serviceability and safety of concrete structures.

Zusammenfassung
Actuators can be used to control the dynamic behavior of vibrating structures. The placement of the actuators in the system has a significant impact on how well adaptive structures perform. The actuator placement for damping particular modes can be assessed using the fraction of modal strain energy. Recent research in structural engineering has demonstrated that the redundancy concept is a useful tool for assessing actuator placement for quasi-static structural behavior because it provides information about the distribution of the degree of statical indeterminacy in the structure. In order to combine fundamental measures from control theory and structural engineering, the similarities between the frequency response function and the redundancy matrix are pointed out. It is shown that, by using the redundancy concept and the fraction of modal strain energy as assessment criteria for actuator placement, adaptive structures can be optimally designed to withstand both static and dynamic loadings.

It is shown that, by using the redundancy concept and the fraction of modal strain energy as assessment criteria for actuator placement, adaptive structures can be optimally designed to withstand both static and dynamic loadings.}, author = {Krauß, Lisa-Marie and von Scheven, Malte and Bischoff, Manfred}, booktitle = {X ECCOMAS Thematic Conference on Smart Structures and Materials, SMART 2023, Patras, Greece}, doi = {10.7712/150123.9826.444394}, title = {Combining the redundancy concept and vibration control for actuator placement in adaptive structures}, year = 2023 }

Taking advantage of adaptivity in the field of civil engineering is an ongoing research topic. Integration of adaptive elements in the load-bearing structure is already well established in many other engineering fields. First investigations promise large material saving potentials also in the field of civil engineering, especially when it comes to high-rise buildings or wide spanned structures like roofs or bridges. In times of emission problems and shortage of materials, the potentials of adaptive civil structures open various new possibilities. In the design and optimization process of adaptive civil structures, we address the differences between classical approaches for passive systems and new practices considering adaptivity. By using a suitable actuator placement, it is possible to manipulate the displacements of the structure as well as the force distribution within the structure. Both material and energy savings can be accomplished with an integrated design of the adaptive structure taking into account the actuation, suitable combination of structural design and actuator placement. For demonstration of the differences in the design process and in the resulting optimized structure, we use a small case study on a truss structure, which is inspired by a high-rise building, and consider static loads.

Zusammenfassung
The coupling of thin, light-weight structures to incompressible flows is a particular challenge within the broad field of computational fluid-structure interaction. The problem is governed by the sensitive and highly non-linear dynamics of slender structures such as shells and membranes in conjunction with the omnipotent incompressibility condition. The contribution presents a partitioned fluid-structure interaction algorithm based on a second order accurate structural solver employing solid shell elements and an Arbitrary Lagrangean Eulerian flow formulation. Stabilized finite elements are used on the fluid domain. Selected aspects of the individual constituents and their interaction are discussed; among them is the problem of conditioning for the shell model, the flow solver satisfying the geometric conservation law and the reliability of the fluid formulation in case of small time steps and distorted mesh. In view of the incompressibility condition the coupling of the two partitions is in particular addressed. It is well-known that sequential coupling approaches, often used for their computational efficiency, may fail in certain situations when the incompressible flow interacts with an extremely slender low mass structure. It could be shown by a rigorous analysis that this is due to the so-called artificial added mass effect. This is an inherent instability of such schemes that unfortunately cannot be removed by reducing the time steps size. As a remedy a strongly coupled partitioning algorithm is applied iteratively adjusting the interface conditions; here different dynamically adapted relaxation methods can be utilized to accelerate the convergence of the iteration. The use of a fully converged coarse grid solution of the coupled problem as a predictor to the iteration scheme can significantly accelerate its convergence and increase the efficiency of the whole coupling scheme. A selection of two- and three-dimensional numerical examples demonstrates the capabilities of the formulation.

Numerical simulation of large scale computational fluid dynamics (CFD) and fluid-structure interaction (FSI) problems is still today a very challenging task. The correct modeling of fluid flow, governed by the instationary incompressible Navier-Stokes equations, and the nonlinear structural behavior are challenges of their own. In addition coupling of both physical fields introduces further requirements on stability and efficiency of the involved algorithms. For this class of problems computing time is still a limiting factor for size and complexity of the problem. Especially for FSI simulations the necessary iterative coupling schemes dramatically increase the required computing time. Here, the use of advanced coupling strategies, reducing either the time needed for one iteration or the number of iterations, can considerably speed up the simulation. We will introduce a class of coupling schemes enhanced by a coarse grid solution to reduce calculation time and accelerate convergence. In addition, the single fields – especially the fluid – demand high efficiency of the solution algorithm. Here, assembly of the element matrices and in particular the iterative solver for the global system of linear equations are the most time consuming parts of the computational process. Very often these algorithms only use a small fraction of the available computer power in scientific codes. Therefore it is highly advisable to take a closer look at the efficiency of algorithms and improve them to make the best out of the available computer power. We will present approaches to significantly increase efficiency in the assembly and solution part of a finite element code. Here, the special features of vector super computers will be exploited.

A numerical approach to simulate the coupled problem of slender structures and incompressible Newtonian flows is described. The formulation is based on a partitioned scheme while finite elements are employed on the single fields. The structural field is discretized in space by finite elements based on a seven-parameter shell formulation capable of dealing with the complex dynamics of very slender structures. An efficient solver for the structural system of equations exploiting an algebraic multigrid approach has been developed. A stabilized fluid element following an ALE formulation of the incompressible Navier-Stokes equations is used to model the flow on a time dependent domain. The geometric conservation law is built in into the formulation to obtain a stable scheme which is second order accurate in time. The accuracy and reliability of the approach with respect to critical parameters such as very small time steps, distorted meshes or steep gradients in particular within the flow field has been analyzed. The approach is able to also deal with free fluid surfaces. The inherent instability of weakly coupled approaches is analyzed which reveals the devastating influence of the so-called `artificial added mass' effect. The convergence of the strongly coupled approach depends on an appropriately chosen relaxation parameter. Ways to automatically adjust the proper amount of relaxation are given. Special emphasis is also put on the efficient implementation particularly of the fluid problem. Vectorization is employed to significantly speed up the time spent for calculating element matrices on vector machines.

In this paper we address various efficiency aspects of finite element (FE) simulations on vector computers. Especially for the numerical simulation of large scale Computational Fluid Dynamics (CFD) and Fluid-Structure Interaction (FSI) problems efficiency and robustness of the algorithms are two key requirements. In the first part of this paper a straightforward concept is described to increase the performance of the integration of finite elements in arbitrary, unstructured meshes by allowing for vectorization. In addition the effect of different programming languages and different array management techniques on the performance will be investigated. Besides the element calculation, the solution of the linear system of equations takes a considerable part of computation time. Using the jagged diagonal format (JAD) for the sparse matrix, the average vector length can be increased. Block oriented computation schemes lead to considerably less indirect addressing and at the same time packaging more instructions. Thus, the overall performance of the iterative solver can be improved. The last part discusses the input and output facility of parallel scientific software. Next to efficiency the crucial requirements for the IO subsystem in a parallel setting are scalability, flexibility and long term reliability.

For the dynamic behavior of lightweight structures like thin shells and membranes exposed to fluid flow the interaction between the two fields is often essential. Computational fluid-structure interaction provides a tool to predict this interaction and complement or eventually replace expensive wind tunnel experiments. Partitioned analyses techniques enjoy great popularity for the numerical simulation of these interactions. This is due to their computational superiority over simultaneous, i.e. fully coupled monolithic approaches, as they allow the independent use of suitable discretization methods and modular analysis software.We use, for the fluid, GLS stabilized finite elements on a moving domain based on the incompressible instationary Navier-Stokes equations, where the formulation guarantees geometric conservation on the deforming domain. The structure is discretized by nonlinear, three-dimensional shell elements. Commonly used sequential staggered coupling schemes may exhibit instabilities due to the so-called artificial added mass effect. As best remedy to this problem subiterations should be invoked to guarantee kinematic and dynamic continuity across the fluid-structure interface. Since iterative coupling algorithms are computationally very costly, their convergence rate is very decisive for their usability. To ensure and accelerate the convergence of this iteration the updates of the interface position are relaxed. The time dependent, ’optimal’ relaxation parameter is determined automatically without any user-input via exploiting a gradient method or applying an Aitken iteration scheme.

Zusammenfassung
Concrete double-curved shell constructions have been used in architectural design and building constructions since the beginning of the twentieth century. Although monolithic shells show a high stiffness as their geometry transfers loads through membrane forces, they have been mostly replaced by the more cost-efficient lattice systems. As lattice systems are covered by planar glass or metal panes, they neither reach the structural efficiency of monolithic shells, nor is their architectural elegance reflected in a continuous curvature. The shells of sand dollars’ – highly adapted sea urchins – combine a modular and multi-plated shell with a flexible, curved as well as smooth design of a monolithic construction. The single elements of the sand dollars’ skeleton are connected by calcite protrusions and can be additionally supported by organic fibres. The structural efficiency of the sea urchin’s skeleton and the principles behind them can be used for innovations in engineering sciences and architectural design while, at the same time, they can be used to illustrate the biological adaptations of these ecologically important animals within their environments. The structure of the sand dollar’s shell is investigated using modern as well as established imaging techniques such as x-ray micro-computed tomography (µCT), scanning electron microscopy and various optical imaging techniques. 3D models generated by µCT scans are the basis for Finite Element Analysis of the sand dollar’s shell to identify possible structural principles and to analyse their structural behaviour. The gained insights of the sand dollar’s mechanical properties can then be used for improving the state-of-the-art techniques of engineering sciences and architectural design.

Zusammenfassung
We present ideas and concepts towards defining a common framework unifying abstract metrics in order to quantify key features of technical load-bearing structures and biological systems. Our aim is to transfer biological concepts to technical systems at this abstract level rather than on the basis of their outward appearance or actual functionality. This means that the biological concept generators for load-bearing structures do not have to be load-bearing structures themselves but may instead achieve rather different functionalities. We intend to carry out this transference by generalizing graph-based abstractions of both technical and biological worlds to allow comparisons to be made at an abstract level. We focus in particular on the intrinsically competing aims of optimality versus multi-functionality and robustness. In this review, we present initial attempts towards defining suitable quantitative measures for robustness to serve as a common ground for studying technical systems and biological systems simultaneously. We discuss generic properties of a ubiquitous signalling network motif and potential relationships to a minimal model for a robust truss structure. These case studies suggest that topological complexity can serve as a common source for a design that is insensitive to perturbations and thus robust in the measures of both worlds.

Zusammenfassung
Coupled problems, like fluid-structure interaction, arise in various areas of engineering. Often they are characterized by high complexity. Especially for three-dimensional problems this results in very long simulation times. In the present work partitioned solution schemes are used for fluid-structure interaction of thin-walled structures and incompressible fluids. The structural domain is governed by the nonlinear elastodynamic equations while the fluid dynamics is described by the incompressible Navier-Stokes equations. Both fields are discretized by finite elements in space and finite difference methods in time. The focus of this work is the development of efficient algorithms for the solution of complex, three-dimensional fluid-structure interaction problems. In the first part of this work the efficiency of the single fields is examined while the second part focuses is on the coupling. For mesh generation in large domains a two level procedure is introduced. A coarse mesh provided by the preprocessor is refined on the high performance computer taking into account the exact geometry. The calculation of element matrices of a finite element code for unstructured meshes can be accelerated on a vector computer by grouping the elements and restructuring the code making use of the advantages of vector processors. In addition, for the solution of the linear system of equations the necessary cpu time can be reduced by the correct choice of iteration scheme and preconditioner. The influence of different parameters on the efficiency of the solver is studied for a fluid simulation. The simulation of interaction between incompressible flows and thin-walled structures often requires implicit i.e. iterative staggered coupling algorithms. Especially for strongly coupled problems the additional iteration leads to very long simulation times. In the present work commonly used iterative staggered coupling schemes are presented in a consistent notation. Using the solution of the coupled problem on a coarse discretization as a predictor the coupling iteration can be accelerated. Finally, convergence rate and calculation time of these new two-level coupling algorithms are compared with other iterative staggered schemes. Numerical examples for the coupling of thin-walled shell structures and three-dimensional flows indicate possible applications of the presented efficient algorithms.
