［摘要］石家庄国际会展中心标准展厅屋盖呈折板形，采用斜放倒三角形空间桁架和变坡次桁架构成的结构体系，巧妙实现了建筑造型，主桁架跨度72m，竖向构件采用钢管混凝土柱。介绍了结构体系及屋盖布置，通过风洞试验得到风荷载取值，给出结构静力、动力及稳定性分析结果，并对关键节点进行验算。分析结果表明在各种不利荷载工况下，结构的周期、位移、应力等指标均满足规范要求，屋盖具有良好的整体稳定性。

Abstract: The roof of the standard exhibition hall of Shijiazhuang International Convention and Exhibition Center has a folding plate shape. The roof is formed by inverted triangular space truss and secondary truss，which elevation varies on the basis of architectural model. The span of the main truss is 72m. The whole roof is supported by concretefilled steel tubular columns. The structure system and the roof arrangement were introduced, and the wind pressure value was decided through the wind tunnel test. The results of the static, dynamic and stability analysis were provided. The sample analysis of important node was carried on. The results of the analysis show that all the period, displacement and stress of the structure fulfill the code, and the whole stability of the roof is good.

Keywords: folded plate; inverted triangular space truss; wind tunnel test; static analysis; stability analysis
