Abstract:Based on the structural system capacity design approach, the structural design of out-of-code building with high-position transfer structure was designed so that the structure has three seismic lines of defense. Vertical stiffness analysis was conducted to ensure good seismic performance; seismic performance indicators were developed, and the elastic analysis under frequent earthquake was conducted as well as elastic analysis under fortification earthquake, non-yielding analysis under fortification earthquake and elasto-plastic analysis under rare earthquake. The seismic response of the whole structure and its components were evaluated. The results show that the whole structure and components can meet the established performance objectives and specifications. The checking and analysis of the key components were complemented, and the weak parts of  the structure were macroscopically analyzed and the corresponding out-of-code strengthening measures were proposed.

Keywords:transfer structure; structural system capacity design approach; seismic performance; elasto-plastic time-history analysis
