The goal of this study is to investigate the effectiveness of the use of multi constructional material in unit module plate of steel grid structure and provide engineers and designers an appropriate view point of multi-material topology optimization when making decision and information in design. The material distribution is implemented with the use of 3 materials in a given plate under prescribed loading and boundary conditions. Topology changes through automatic distribution of multi materials are presented during optimization procedures showing that there could be selective structural design possibility when using multi materials. The cross sections, stiffness and cost of material combination are useful information for engineers and designers in making design decision.
