摘　　要：以四层回形框架结构为例,分析了墙式钢纤维复合金属抗震阻尼器在框架结构中的消能减震效果,采用PKPM软件和Midas Gen软件分别进行了中震下反应谱分析和中震时程分析下附加阻尼比的对比,并进行了消能器耗能占比分析。结果表明:中震反应谱法计算的实际附加阻尼比均低于中震时程分析和能量比法计算的附加阻尼比,说明结构在中震反应谱下的分析结果偏于安全;墙式钢纤维复合金属抗震阻尼器对结构消能减震效果明显。This study took a four-story circular frame structure as a case study to analyze the energy dissipation and seismic reduction effect of wall-type steel fiber composite metal seismic dampers in frame structures.PKPM software and Midas Gen software were used to compare the additional damping ratio under medium earthquake response spectrum analysis and medium earthquake time history analysis,respectively.An energy dissipation ratio analysis was also performed.The results show that the actual additional damping ratio calculated by the medium earthquake response spectrum method is lower than that calculated by the medium earthquake time history analysis and the energy ratio method,indicating that the analysis results of the structure under the moderate earthquake response spectrum method are safe.Wall-steel fiber composite metal anti-seismic dampers have obvious effects on structural energy dissipation and seismic reduction.
