Abstract:The reinforced concrete frame-shear wall structure system was adopted in tower 2A# of Huilong Commercial Center. To meet the requirements of the atrium set around the building at different elevation, transfer structure with V shaped brace was used for the transformation of upper structure. The structure was analyzed by YJK and ETABS programs for response spectrum analysis and complementary elastic time-history analysis under the frequent earthquake. Elastic-plastic time-history analysis of the structure was performed by MIDAS Building program under rare earthquake. The stress analysis of the floor slab at the transition V-shaped brace was carried out. In addition, the construction simulation analysis and the finite element analysis of the joints were also carried out. Analysis results show that the overall structural system is rational and has a good seismic performance, the overall seismic performance of the structure can meet the C-level performance target of  Technical specification for concrete structures of tall buildings (JGJ 3—2010), and the deformation of the whole structure and the stress levels are in a reasonable range.

Keywords:overrun tall building; outside frame not closed; frame-core wall structure; response spectrum analysis; transfer structure; time history analysis
