Calculation of the redundancy with changing structure

Project description

Background

Architecture is of central ecological, economic, social and cultural relevance. Over the next 35 years, urban buildings for an additional 2.6 billion people need to be constructed. One of the key objectives of the Cluster of Excellence is to develop a methodology of “Co-Design” based on interdisciplinary research in architecture, structural engineering, systems engineering, robotics, building physics, computer science and social science. The Cluster will make a significant contribution to providing the prerequisites for a high-quality, liveable and sustainable built environment and a digital building culture.

State of the art

Based on the work of the first subproject with respect to alternative performance indicators of structures, such as imperfection sensitivity and buildability, the developed methods are further refined. With the help of an interactive agent-based modeling and simulation method (ABMS), it is possible to represent structural mechanical properties based on the redundancy matrix within the framework of structural design and to make them available to designers. This allows mechanical properties to be considered in addition to geometric constraints during design.

Project goals

Part of the work within the research project is concerned with the visualization of mechanical properties in early design phases, which are intended to support structural assessment and thus accelerate and improve the design process. A central aspect here is the visualization of results of three-dimensional beam structures.

Optimization based on alternative performance indicators

In addition, a better prediction of the actual structure as well as its properties should be made possible, whereby relevant parameters of the structural response can be identified. The overall objective is to reduce the required partial safety factors in the design and the associated material costs of fiber composite structures.
