Abstract: Truss transformation structure has lots of advantages, such as reasonable in load-bearing, small to earthquake reaction, flexible in building layout, large in useful space, and convenient and quick in pipe arrangement. But depending on experience to design is not enough because of the complex structure form. Based on the site engineering example of the multi-layer truss transformation structure, using the HYPERMESH-OPTISRUCT topology as the main technical way and engineering model test, the optimum arrangement of the structure was researched.

Keywords: multi-layer truss transformation structure; topology optimization; HYPERMESH-OPTISTRUCT
