摘要
本文简要对比了目前常用的抗震加固方法;介绍了屈曲约束支撑及粘滞阻尼器这两种消能减震元件的特性,以及它们在结构抗震加固中的应用;阐述了采用屈曲约束支撑及粘滞阻尼器进行联合消能减震的抗震加固技术,并结合一栋既有综合楼的抗震加固设计,给出了这种联合消能减震技术的应用方法,计算分析结果表明了这种方法的有效性。
In this paper,the traditional and new seismic strengthening methods were summari zed and compared.Two energy dissipation devices,the buckling-restrained brace s and viscidity dampers,were introduced as well as the application of them to s eismic strengthening.A new energy dissipation technology for seismic strengthen ing with the combined use of buckling-restrained braces and viscidity dampers w as proposed emphatically.Then,this new technology was used for the seismic str engthening design of an existing building.The seismic analysis results of this building verified the effectiveness and performance of this new seismic strength ening method.
