摘　　要：为研究大底盘双塔建筑的结构抗震安全性,文中以广州某艺术图书楼为例,并根据其结构特点、结构超限等情况,通过采用振型分解反应谱法、弹性时程分析法以及动力弹塑性时程分析法对整体结构进行抗震性能化分析,并针对薄弱部位提出相应的抗震加强措施。结果表明结构可满足设定的C级性能目标。为类似工程的应用实践提供参考。A certain art library building in Guangzhou is taken to study the structure seismic safety of a large-base twin-tower building.Based on the structural characteristics and structural exceedance item,the overall structure is analyzed for seismic performance using the modal decomposition response spectrum method,elastic time history analysis method,and dynamic elastic-plastic time history analysis method.Corresponding seismic strengthening measures are proposed for weak parts.The results show that the structure can meet the set C level performance target,providing reference for similar engineering applications.
