［摘要］深圳国际会展中心由展厅、登录大厅、中央廊道等组成。标准展厅屋盖跨度99m，采用立体桁架作为其主承力体系，标准展厅间采用跨度为42m的立体桁架形成整体，两端带悬挑跨。对标准展厅屋盖及悬挑桁架进行了风洞试验以确定风荷载计算参数。介绍了标准展厅主体结构选型、结构布置等结构设计基本情况，对结构静力、动力和稳定性分析以及节点设计、施工模拟等内容做了阐述，并对标准展厅结构进行了罕遇地震作用下的动力弹塑性时程分析以研究结构的抗震性能。研究结果表明，标准展厅结构设计能够较好地满足结构安全性要求和结构合理性要求，结构安全、可靠。

Abstract:Shenzhen International Convention and Exhibition Center is composed of exhibition hall, lobby and central corridor. The span of the standard exhibition hall roof is 99m, and the three-dimensional truss is used as its main load-bearing system. The standard exhibition hall is formed by a three-dimensional truss with a span of 42m to form a whole. Wind tunnel tests were performed on the roof and cantilever trusses of the standard exhibition hall to determine wind load calculation parameters. The basic structural design conditions were introduced such as the selection of the main structural system and the structural layout of the standard exhibition hall. The static, dynamic and stability analysis of the standard exhibition hall structure, the design of the joints, and construction simulation were explained. Elasto-plastic time-history analysis on the standard exhibition hall was conducted to study the seismic performance of the structure under the rare earthquake. The research results show that the standard exhibition hall structural design can well meet the requirements of structural safety and structural rationality, and the structure is safe and reliable.

Keywords:Shenzhen International Convention and Exhibition Center; exhibition hall; main structural system selection; construction simulation; overall stability analysis; elasto-plastic time-history analysis
