摘要
采用SAP2000软件分别建立一字型RC框架结构及设置黏滞阻尼器的RC框架结构模型并进行模态分析、反应谱分析和线性时程分析,并对结构的自振周期、楼层位移及层间位移角等动力特性进行了对比分析,结果表明:结构增设阻尼器后可以有效改善结构的抗震性能,并且可以大幅减少结构的层间位移及层间位移角等性能指标。
The seismic response of a zigzag RC frame structure is analyzed by using SAP2000 software.The modal analysis,response spectrum analysis and linear time history analysis of the original structure and the energy dissipation structure with viscous dampers are carried out respectively,and the dynamic characteristics of the structure such as natural vibration period,floor displacement and inter-story displacement angle are compared.The results show that the seismic performance of the structure can be improved effectively by adding dampers,and the performance indexes such as inter-story displacement and interstory displacement angle can be greatly reduced.
