Samenvatting

This presentation is the first on 20 years of research on the failure mechanisms of sheeting subjected to combined concentrated load and bending moment, performed at Technische Universiteit Eindhoven. The aim of this research is to develop accurate, insight providing design rules using simple mechanical models, based on observed failure modes. The presentation summarizes the performed experiments, finite element simulations, and analytical models. It is concluded that mechanical models may be feasible only for sheeting without stiffeners in web and flanges. For sheeting with stiffeners, the models become so complex that it is not likely that they will lead to simple design rules. Secondly, to understand the spatial and structural building design process and to help designers, the idea of a research engine has been developed. In this engine cyclic transformations take place between spatial and structural building designs. With this engine, a design process can be studied closely and subjected to improvement, and designers can be supported. Within the research engine, architectural elements are transformed into structural elements only for a certain step. Hence the resulting structural topologies are not a-priori kinematically determined. Therefore, in the next step, one of the problems to solve is the exact description of a kinematically indeterminable topology (ie. at which nodes do spatial freedom exist and in which direction). During the presentation, a method for this description and its implementation will be presented.
