摘要
文章利用有限元分析软件Perform-3D,选取新型内嵌黏滞阻尼器装配式钢框架作为研究对象,对比分析内嵌黏滞阻尼器的新型装配式钢框架与普通钢框架的抗震性能;采用基于能力谱的Pushover方法,对基底剪力-顶点位移、最大层间位移角和最大楼层位移等关键参数进行考察。结果表明,新型内嵌黏滞阻尼器装配式钢框架的抗震性能明显优于普通装配式钢框架。
The article uses finite element analysis software Perform-3D to select a new type of prefabricated steel frame with embedded viscous dampers as the research object,and compares and analyzes the seismic performance of the new prefabricated steel frame with embedded viscous dampers and the ordinary steel frame.The Pushover method based on capability spectrum is used to investigate key parameters such as base shear vertex displacement,maximum inter story displacement angle,and maximum floor displacement.The results show that the seismic performance of the new embedded viscous damper assembled steel frame is significantly better than that of the ordinary assembled steel frame.
