Abstract

For the development of a structural topology, structural grammars predefine locations of structural mass based on the building spatial design, whereas topology optimisation distributes structural mass freely and based on the loads. This paper presents a new method that involves first an iterative structural grammar that uses finite element simulations to optimise an initial structural topology for minimal structural mass. Hereafter topology optimisation is applied to modify the structural topology elements for minimal compliance. Due to the several groups of structural topology elements involved, a separate volume fraction is maintained for each group. Using an academic case study, the method is compared to standard structural grammars and topology optimisation, defining Pareto fronts for the objectives structural volume and strain energy. Future research will focus on the development of structural grammars that take into account openings, and on the implementation of the new method in simulations of co-evolutionary design processes.
