Summary

The goal of this paper is to design steel reinforcement of the building frame such as a diagrid structure using topology optimization, which is well-known as an optimal material distribution tool to extract both an optimal shape and a topology, i.e. the connectivity of members under a given material quantity. The topology optimization problem presented in this study is to determine the layout of material of specified volume in a domain that maximizes the first natural eigenfrequency for dynamic responses and minimizes the strain energy for static responses under a given set of boundary conditions.

This study targets two facts as follows. One is to evaluate the desired angles of diagonal members consisting of DiaGrid for conceptual design of buildings with respect to stiffness of optimal topology. The other is to investigate or understand the global and topological DiaGrid mechanism by using the topology optimization technique. This study provides both a design and analysis tool for DiaGrid structural designs and DiaGrid structural analyses. An appropriate DiaGrid structure can be achieved or measured as a design model by considering both static and dynamic behaviors.

According to the evaluated topology results of numerical examples, it is verified that DiaGrids are redundant and loads follow the diagonals through the structure as it naturally resists vectors of forces through its triangulation.
