摘要
简要介绍了基于位移的防屈曲支撑抗震加固简化算法,结合一幢6层既有综合楼进行实例分析,并通过弹塑性时程分析予以数值验证。结果表明,简化算法能够快速进行支撑用量估计,其减震效果与时程分析结果基本一致。
In this paper, a seismic strengthening method based on performance with buckling-restrained braces is briefly introduced. The simplified method is applied to an existing building. The results of nonlinear time history analysis are compared to results of the simplified method. The results prove that the energy dissipation of simplified method is similar with that of history analysis.
