摘要
简要介绍了Sap2000中FNA方法的计算原理,结合既有综合楼采用消能减震技术进行了加固设计。通过对原结构地震反应分析,对抗震能力不足之处采取消能加固。结果表明,加固后有效降低了结构地震反应,达到抗震性能要求。
In this paper, a method on fast nonlinear analysis of Sap2000 soft is briefly introduced. Energy dissipation and seismic strengthening technology is applied to an existing building. According to the insufficiency of original structure seismic behaviors, the project by using energy dissipation braces with viscous damper is proposed,and the main results are also given. The analysis results prove that the vibration response of the structure with energy dissipation devices could be effectively reduced.
