摘要
给出了墙式铅剪切阻尼器的构造,然后基于某实际工程,通过PERFORM-3D分别建立了未控结构、支撑式减震结构及墙式减震结构的有限元模型,进行了结构在罕遇地震下的动力弹塑性时程分析,结合结构响应分析了铅剪切阻尼器的减震控制效果,重点研究了支撑式减震结构和墙式减震结构在地震作用下结构响应的不同之处。对比分析发现,不管是从耗能角度还是从对结构影响的角度,墙式铅剪切阻尼器均优势明显。
The construction of wall-type lead shear damper is proposed in this paper and finite element model of structure without damper, structure with brace-type lead damper and structure with wall-type lead damper are built. The different reactions to dynamic time history under rare earthquake are discussed, especially the difference between structure with brace-type damper and structure with wall-type damper. The results show that wall-type damper has more advantages on energy dissipation.
