（哈爾濱工業(yè)大學(xué)土木工程學(xué)院，150090）［提要］哈爾濱國際會議展覽體育中心是國內(nèi)在建和已建成的展覽類建筑中規(guī)模較大的一個。主要介紹了其組成及結(jié)構(gòu)形式，主館大跨鋼結(jié)構(gòu)的設(shè)計過程。重點闡述了主館大跨張弦桁架體系的結(jié)構(gòu)特點和設(shè)計中參數(shù)的選擇；應(yīng)用ANSYS軟件及自主開發(fā)的輔助接口程序，對主體鋼結(jié)構(gòu)進(jìn)行了細(xì)致的受力分析。在優(yōu)化設(shè)計的基礎(chǔ)上，對施工過程進(jìn)行了全過程數(shù)值模擬，有效地指導(dǎo)了施工中的預(yù)應(yīng)力張拉的實時監(jiān)測和施工調(diào)整控制。分析了張弦桁架的施工穩(wěn)定性，同時總結(jié)了該類結(jié)構(gòu)體系的一些設(shè)計特點。［關(guān)鍵詞］鋼結(jié)構(gòu)；張弦桁架；ANSYS軟件；施工數(shù)值模擬；施工控制Design of String Structure in Harbin International Conference Exhibition and Sports Center/Fan Feng, Zhi Xudong, Shen Shizhao(School of Civil Engineering, Harbin Institute of Technology, Harbin 150090, China)Abstract:Harbin international conference exhibition and sports center is a comprehensive public service. It is a larger one among the domestic exhibition architectures which are under construction and constructed. The composition, the structural form and the design process of the large-span steel structure of the main exhibition center are introduced. The selection of design parameters of the large-span truss cable structural system of the main exhibition center is presented. By utilizing the software ANSYS and the self-developed assistant interface programs, loadbearing analysis of the main steel structure is carried out. On base of the optimizing design, the wholecourse numerical simulations in construction are carried out, which effectively guides the synchronized monitoring of pretension and adjusting control in construction. The stability of truss cable structure in construction is analyzed and several design characteristics of this kind of structural system are concluded.Keywords:steel structure; truss cable structure; numerical simulation; construction; design
