[摘要]长春市十一高中北湖学校B区为复杂连接的超限结构,属于错层连体结构,采用框架-剪力墙结构体系。根据超限情况和性能设计目标,进行小震弹性设计。对结构关键构件采用等效弹性方法进行中震、大震作用下的性能设计,采用大震弹塑性时程分析法评价结构的承载力能力和变形能力;对连接体部位节点进行von Mises 应力分析,对连接体部位的楼板进行大震作用下的抗剪承载力验算。最终提出结构的抗震加强措施。

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
