摘要
利用粘滞阻尼器对工程结构进行减震是耗能减震方法中最有效的新型抗震技术之一。结构设计中通常是粘滞阻尼器与钢支撑串联形成粘滞耗能支撑,并将其附设于结构层框架柱之间。粘滞耗能支撑具有显著的耗能特性,可有效地减小建筑物的地震反应。本文结合一采用钢支撑进行抗震加固改造的工程实例,通过粘滞耗能支撑设计对原结构进行耗能减震研究,并进行了粘滞耗能支撑结构的弹塑性地震反应动力时程分析。
Energy dissipation is a new kind of antiseismic technology. Structural shock absorption by viscous dampers is one of the most effective energy dissipation methods. In general, viscous energy dissipation brace (VEDB) is designed by viscous damper series connected with steel brace, and it is placed between two interlayer frame posts. VEDB have excellent damping ca- pacity and it can effectively reduce structure's earthquake response. On the basis of one antiseismic strengthening and rebuilding practical frame fitted with ordinary steel brace, this paper will have an energy dissipation study on the primary frame fitted with VEDB, and it mainly studies on the elastoplastic earthquake dynamic response time-history analysis of VEDB structure.
