Abstract:The overall appearance of Exhibition Center in Lishui Zijin (Yong Yang) Industrial Park is a complicated space spherical surface. Lightweight large-span spatial single-layer reticulated shell structural system was adopted. In the design process, the effects on the structure were analyzed including constant load, live load, wind load, temperature and earthquake action, and the various working condition were combined to analyze static and dynamic characteristics of structure, bearing capacity of components and structure stability. Analysis results show that using topology to determine component shape can optimize components. High curvature spatial hyperboloid provides a good overall stability for latticed shell structure. Application of direct analysis and design method in stability analysis of latticed shell can accurately reflect the mechanical and stability conditions, when considering the initial geometric imperfection in overall structure and components.
Keywords:spatial spherical surface; single-layer spherical latticed shell; dynamic analysis; stability analysis; direct analysis and design method
