[摘要] 桁架转换结构具有受力明确、传力途径清楚，结构重量轻、地震反应小，大型设备布置更加灵活等优点，适合转换层的大跨度转换，但又由于其结构形式相对复杂，依靠经验做设计存在较多的模糊性和局限性。以叠层桁架转换结构工程实例为基础，采用HYPERMESH-OPTISTRUCT拓扑作为研究的主要技术手段，以工程模型试验作为验证方法，研究叠层桁架转换结构优化布置的规律。

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
