摘要：
The entire building of the Shijiazhuang International Exhibition Centre project is ascetically novel, distinctive and structurally creative. It has a complicated load carrying system. The vertical load is sustained in the form of a self-anchored cable suspended structure and the horizontal load carrying system adopts a double-layer cable truss structure which has special force transmission mode. In order to increase the stiffness of the roof plane, horizontal cross support is also provided. In the analysis, the structure of Hall C of Shijiazhuang International Convention and Exhibition Center was considered as the research object, where linear buckling and nonlinear buckling analysis were conducted. The influences of the initial defect layout, load distribution and the initial imperfection value on the overall stability of the structure were studied and compared. The results show that the layout of the initial imperfections is insensitive to the overall stability, and the load distribution form has a significant influence on the overall bearing capacity of the structure. When the initial imperfection amplitude is within 1/300 of the structural span, the overall bearing capacity loss is not significant, but when the value increases to 1/100, the overall bearing capacity of the structure decreases significantly. The structure has good overall stability, and both the linear and nonlinear critical buckling capacity satisfy the codified requirements. © 2020, Editorial Office of Journal of Building Structures.
