Visualisation and Research Strategy for Computational Spatial and Structural Design Interaction

Abstract: At the department of Architecture, Building and Planning of the Eindhoven University of Technology, a new research project has recently been initiated with the goal to develop a research engine for studying the interaction of spatial and structural design processes. Each design process will be implemented as two separate configurable transformation steps; a conversion step and an optimisation step. The idea is to start with an initial spatial design and measure how the design changes after subsequent iterations through the conversion and optimisation processes. A significant part of the spatial-to-structural conversion step together with a first version of a visualisation tool have been implemented and both perform as expected. During the course of the research project, a first version of the complete research engine will be developed. The performance of this first version will be compared to case studies. Based on these results, adjustments and/or additions to the research engine’s transformations will be made. The final version of the research engine will also be used to experiment on academic designs in order to develop insights in the fundamental relation between space and structure.

Redefinition of geometrical components to specify kinematically undetermined behaviour

Abstract: A method for the redefinition of geometrical design components, to be used for specifying kinematically undetermined behaviour, is presented. It starts with checking all line-line combinations for intersection or for a line-line combination being collinear. If an intersection has been found, it is used to generate additional lines such that both old lines are split up at their intersection, resulting in new lines. For lines being collinear a similar approach is followed. Hereafter, all line-area combinations are checked. If certain conditions are met, new intersection points and lines are generated in the area to provide new areas that split up the old area correctly. The procedures (line-line and line-area) are repeated until convergence. Finally, pattern recognition is used to find all areas from the intersection points within an original area. A C++ program and a number of examples verify the method and test its efficiency.

Positioning FEM in the transformation of spatial design to structural design

Abstract: In the field of architecture, structural topology is the set of locations, types (i.e. beams, columns), and ar-rangements of structural elements. To help the architect in understanding the structural topology for his spatial design, research exists that studies the process of the transformation of a spatial design into a structural design. If the Finite Element Method (FEM) is applied in this research, two problems can occur: (1) how to transform a topology in a me-chanical system and FEM-input and (2) how can FEM support qualitative design decisions. In this paper, it is tried to define these two problems more clearly by developing data(EXPRESS)- and process(IDEF0)-models for three trans-formations: From structural topology to mechanical system, from mechanical system to finite element model, and from finite element model to design recommendations. A six-level apartment building is used as a case study to test and sup-plement the data- and process-models for all three transformations. It can be concluded that the data- and process models are useful at their abstract level, but that many problems at lower abstraction levels remain to be solved.
