Abstract: Wuxi Harmony Commercial Complex is a particularly irregular structure. The special?shaped steel dome adopts asingle?layer reticulated shell structure with a maximum span of about 19m and a maximum cantilever length of about 7m.Special?shaped steel dome spans the seismic joints of the lower concrete structure and is supported on 12 tree?shaped on thebifurcated column. The roof structure system, static, dynamic and stability analysis and joint design of structural wereintroduced. Aiming at the characteristics of the cross?joint connection in this project, various finite element softwares wereused to establish single and integral models, and the interaction between the lower concrete structure and the upper domesteel structure was analyzed. According to the structural characteristics, reasonable performance targets were set to ensurethe seismic performance level of key components. The analysis results show that the structural system has good stiffness andseismic performance, and the structure is safe and reliable.
Keywords:Wuxi Harmony Commercial Complex; irregular structure; special?shaped steel structure dome; single?layerreticulated shell; siamese structure; seismic performance design
