吳斌杰(中國建筑設計研究院上海分院，上海200120)[摘要] 桁架轉換結構具有受力明確、傳力途徑清楚，結構重量輕、地震反應小，大型設備布置更加靈活等優(yōu)點，適合轉換層的大跨度轉換，但又由于其結構形式相對復雜，依靠經(jīng)驗做設計存在較多的模糊性和局限性。以疊層桁架轉換結構工程實例為基礎，采用HYPERMESH-OPTISTRUCT拓撲作為研究的主要技術手段，以工程模型試驗作為驗證方法，研究疊層桁架轉換結構優(yōu)化布置的規(guī)律。[關鍵詞] 疊層桁架轉換結構；拓撲優(yōu)化；HYPERMESH-OPTISTRUCT中圖分類號：TU318 文獻標識碼：A 文章編號：1002-848X(2012) S2-0376-05Application of the topology optimization to multi-layer truss transformation structure in conceptual design phaseWu Binjie( China Architecture Design & Research Institute, Shanghai 200120, China)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
