Investigation on material layouts of structural Diagrid frames by using topology optimization

This study shows a computer-oriented design tool conceptually extracting a so-called steel-framed "Diagrid", which has been wellknown as a specific and effective structural unit cell for mainly free-formed building frames. The goal of this study is to provide a smart design optimization task to measure the effects of variation of optimally geometrical configurations like shape and topology of the diagrid to structural engineers. Numerical applications verify how optimal solutions by using the present topology optimization design tool can evaluate promising possibility to conceptually generate practical diagrid unit cells as a trial of building related issues.
