Abstract

This paper outlines a method for the geometry optimization of space frame structures for joint uniformity. Joints are one of the main drivers for the constructibility of space frames, as they represent a high percentage of the overall material and fabrication cost. They are studied in relation to the geometrical complexity of the design surface and the fabrication process applied. A computational workflow is proposed for their geometrical optimization, which comprises of three steps: the comparison and identification of varying joint configurations within a structure, their clustering into a minimum number of groups that satisfies a given tolerance, and finally their geometrical optimization for joint uniformity. The efficiency of the proposed workflow is validated through a variety of examples and comparisons. Developed in a intuitive user-interface environment, it allows designers to carry out early design studies to minimize the construction cost of their proposals and enhance the application of informed space frame designs in practice.
