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
