Project description

Background

Since the early 1970s, structures that can react automatically to a change in external loads or boundary conditions have been investigated in the USA. Mainly the aerospace industry was interested in these developments, as they lead to economic lightweight structures. In the last few years, sustainability and economical lightweight structures have played a major role in construction, which is why adaptive systems are becoming the focus of research. There are various application fields where adaptive systems offer efficient solutions. Mainly the aims are to influence design-decisive peak loads, to homogenize stress states and to reduce deformations.

Adaptivity of structures describes the ability to react automatically to a change in external loads or boundary conditions. This reaction can be carried out in various ways, e.g. changes of geometry, forces or material properties, which can be made by actuators. The control of the actuators requires a sensor system, which is able to detect the effects of the changes on the load-bearing structure. Thereupon a controlled reaction of the actuator system can be executed in order to configure the load-bearing structure optimally for the prevailing situation.

Characterization of adaptive structures

Crucial for the work with adaptive systems is the definition of what an adaptive system exactly is. The required terminology, which is quite different in the fields of mechanical-, control- and civil-engineering, has to be brought together. In order to compare different designs, objective measures to value an adaptive system are needed. They can be calculated using redundancy contributions, gramian controllability matrices or similar. These matrices contain information, which can be used for an optimized placement of actuators in the structure. This is a crucial point in the assessment of the performance of an adaptive structure. Using a suitable actuator placement and control, e.g. stiffness-governed design tasks can be transferred into strength-governed tasks. For example, in the design of high-rise or wide spanned structures, the design decisive results can be deformations or accelerations in the structure. A well-designed adaptive structure is able to manipulate those quantities in order to reduce the amount of matter significantly, which is needed in the primary structure to comply with constraints.

Comparison of results for a sizing of the cross sections of a passive (left) and an adaptive Structure (right) subjected to the same load cases and constraints. The maximum utilizations of the cross sections (a) are larger in the adaptive structure, therefore smaller cross sections (b) are necessary, what leads to a lighter structure.

Modelling of the actuation

The focus in this research area is the modelling and simulation of adaptive systems. To carry out an exact analysis, which represents the behaviour of the adaptive structure realistically, the actuators, sensors and control technology must be integrated into the model. This is also beneficial in the development of algorithms that control the system. Towards an efficient simulation of adaptive structures using the finite element method, suitable finite actuator elements are defined.

Abstract
This paper discusses the role that structural stiffness plays in the context of designing adaptive structures. The focus is on load-bearing structures with adaptive displacement control. A design methodology is implemented to minimize the control effort by making the structure as stiff as possible against external loads and as flexible as possible against the effect of actuation. This rationale is tested using simple analytical and numerical case studies.

Anschließend werden in einer systematischen Studie die Auswirkungen der Aktuierung auf den Tragwerkszustand und die damit erreichbaren Ziele quantifiziert. Dazu werden die Einflüsse verschiedener Parameter, wie z. B. die Anzahl an Aktoren, der Grad der statischen Unbestimmtheit und das globale Tragverhalten, untersucht.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
This contribution proposes a new approach to derive geometrically parameterized, reduced order finite element models. An element formulation for geometrically parameterized finite elements is suggested. The parameterized elements are used to derive models with a parameterized geometry where the parameterized system matrices are expressed in an affine representa- tion. Parametric model order reduction can then be efficiently used to reduce the full order parameterized model to a reduced order parameterized model. The approach shows two beneficial features. First, design studies and shape optimizations can be conducted with parameterized reduced order model of much lower dimension compared to the parameterized, full order model. Second, it is possible to compute sensitivities analytically, and therefore, to avoid the computation of finite differences gradients. The approach is illustrated with two numerical examples. The first example includes a detailed error analysis. The second example is a shape optimization example of an adaptive structure.

Abstract
In this contribution, coupled, parameterized second order systems are considered where the coupled, parameterized system is derived from the assembly of several parameterized component models. Two approaches for the Parametric Model Order Reduction of such coupled systems are presented and compared in a reduced order shape optimization example. In the first approach, the coupled, parameterized system is derived by coupling the parameterized, full order component models. Then, Parametric Model Order Reduction is executed for the coupled system. In the second approach, the parameterized, component models are first reduced independently of their actual mounting situation. Afterwards, the parameterized, reduced order component models are coupled to derive the parameterized, reduced order system model. It is shown that the first approach yields smaller parameterized, reduced order system models. However, the second approach allows to reuse and to recombine the parameterized, reduced order component models arbitrarily. It therefore introduces more flexibility in the modeling process, enabling for example a toolbox based optimization with parameterized, reduced order models.

Abstract
In 2017, the University of Stuttgart started a Collaborative Research Centre with the title Adaptive Skins and Structures for the Built Environment of Tomorrow. The goal of this research project is to find an answer to today’s most urgent social and ecological questions as the global population continuously increases and the available resources remain limited. As the central approach to the solution of this problem, adaptive elements will be included in the structure, the interior and the façade of an experimental 37 m tall building. This paper introduces the topic of adaptivity in building structures and provides an overview of the research topics applied in this globally unique adaptive high-rise building. Due to the complexity of research topics of this Collaborative Research Centre, this paper only covers the research concerning the experimental high-rise building.
