［摘要］石家庄国际展览中心展厅采用纵向索通过受压竖杆支撑横向索的双向悬索结构体系，主承重方向为主索及受压竖杆，次承重方向为索桁架，双向均为平面柔性结构，两者相互垂直布置互为面外支撑。通过施工阶段模拟分析，考虑几何非线性建立施工完成态模型，再针对其进行静载、风、温度、地震等工况及组合工况下结构性能进行分析；对结构体系中关键受压构件，如自锚杆、A形柱等进行了稳定性分析；通过设置上下弦杆及屋面边桁架，提高了结构抗连续倒塌能力。

Abstract:The exhibition hall of Shijiazhuang International Exhibition Center adopts a bidirectional cable structural system in which the longitudinal cable supports the transverse cable through the compression vertical bar. The main bearing direction is the main cable and the compression vertical bar, the secondary bearing direction is the cable truss, and the two directions are plane flexible structures. The two are arranged vertically and mutually as the out of plane support. The simulation analysis of the construction stage was conducted considering the geometric nonlinearity, and the completed state model of the construction was established, and then the static load, wind, temperature, earthquake and other working conditions and combined working conditions were analyzed. The stability analysis was carried out of the key compression components in the structural system, such as self-anchored bar, A-shaped column and so on. The resistance to progressive collapse was improved by setting up the upper and lower chord and roof side truss.

Keywords:Shijiazhuang International Exhibition Center; bidirectional cable structure; construction completion state; self-anchored bar; resistance to progressive collapse
