Abstract:Scientific research A3 building of InSigma ZhunQian is a large cantilever structure with multiple out-of-code items, which belongs to a special irregular structure. The project adopts the mixed structural system of steel frame, central support and steel plate composite shear wall/steel reinforced concrete shear wall. Appropriate performance targets were selected, performance-based seismic calculation, elastoplastic dynamic time-history analysis and floor elastoplastic analysis were conducted for the whole structure and components, and special joins were analyzed. The results show that the steel plate composite shear wall and the central support structure used in this type of large cantilever structure can exhibit good performance under gravity loads and rare earthquakes.

Keywords:large cantilever; steel plate composite shear wall; central support; steel reinforced concrete shear wall; joint analysis; elastoplastic dynamic time-history analysis
