Abstract:Eleventh high school of Beihu in Changchun is a complex out-of-code connected structure with staggered floors, and it adopts the frame shear wall structural system. According to the out-of-code situation and the performance design objectives, elastic design was conducted on the structure under frequent earthquake. Equivalent elastic methods were used to conduct performance design on key components of the structure under fortification and rare earthquakes. The elastic-plastic time-history analysis method was used to evaluate the bearing capacity and deformation capacity of the overall structure under rare earthquake. The von Mises stress analysis was performed on the joints at the connected parts to check the shear strength of the slabs at the connected parts under rare earthquake. Finally, the seismic strengthening measures of the structure were put forward.

Keywords:connected structure with staggered floors; performance design; equivalent elastic; elastic-plastic time-history analysis; seismic strengthening measure
