摘要

采用非线性分析软件ABAQUS对设置金属阻尼器的某大型主厂房进行罕遇地震作用下的弹塑性分析,分析结果表明:设置金属阻尼器以后,结构的层间位移角和构件损伤明显减小,结构的抗震性能显著提高,在罕遇地震作用下能够满足"大震不倒"的性能要求。
        The nonlinear analysis software ABAQUS is used to do elastoplastic analysis for a large main workshop with metallic damper under severe earthquake. The analysis results show that: after setting metallic damper,the interlayer displacement angle and component damage of the structure significantly decrease,and the seismic performance improves significantly,so the structure can meet the performance requirements of the"flame to fail"under severe earthquake.
