［摘要］晋中市档案馆由于存在分塔、大跨度连体、楼板不连续、平面不规则等超限复杂项，对结构进行性能化抗震设计及弹性时程分析、模拟中震分析和大震动力弹塑性时程分析。结果表明，结构整体指标、关键构件和一般构件均能满足预设的抗震性能目标。针对结构具有的扭转不规则及以上平面不规则等抗震不利情况，对大震弹塑性分析揭示的结构薄弱部位进行了相应加强措施，如提高关键剪力墙抗震等级，在墙体端部设置钢骨，连体部分楼板均双层双向配筋，有效保证了结构的抗震安全。

Abstract:Due to the out-of-code complexity of tower separation, large-span connection, slab discontinuity and plane irregularity, the performance-based seismic design and elastic time history analysis, simulated moderate earthquake analysis and large earthquake dynamic elastic-plastic time history analysis were carried out on the structure. The results show that the overall structural index, key components and general components can meet the preset seismic performance targets. In view of the unfavorable anti-seismic conditions of the structure, such as torsional irregularities and irregularities in the above plane, corresponding strengthening measures were taken for the weak parts of the structure revealed by elastoplastic analysis of rare earthquake, such as improving the seismic grade of the key shear wall, setting steel bars at the end of the wall and double-layer two-way reinforcement for the connecting part of the floor, which effectively guarantees the seismic safety of the structure.

Keywords:out-of-code structure; aseismic performance-based design; large-span connection； steel truss
