摘要/Abstract

摘要： 研究一种震后可替换的新型复合阻尼器置于连梁跨中以实现保护连梁并提高连梁耗能能力的目标.在ABAQUS有限元软件平台上根据复合阻尼器的特点提出一种可以有效反映其特征的等效简化模型,并与仿真模型进行对比验证;将等效简化模型应用于高层剪力墙结构的连梁中,进行罕遇地震下的剪力墙结构动力时程分析;以混凝土连梁为参照,研究安装了复合阻尼器后的连梁串联刚度的取值对结构减震效果的影响.结果表明:等效简化模型能较好展现复合阻尼器的特性;安装复合阻尼器能有效减少结构的层间位移、基底反力和损伤;耗能连梁的替换刚度比取0.4时,可以获得较好的结构减震效果.

Abstract: An innovative compound damper which can be replaced after earthquake is studied. The compound damper can be installed at the middle of coupling beam to protect the wall and improve the capacity for dissipate energy of coupling beams. Based on ABAQUS procedure, an equivalent simplified model which can effectively reflect characteristics of compound dampers are proposed and compared with the simulation model. The equivalent simplified model is used in the shear wall structure with coupling beams, and dynamic time history analysis is carried out under the rare earthquake. Taking the concrete beam as a reference, seismic performance influenced by alternative stiffness of beams which are installed the compound dampers are studied. The results show that the equivalent simplified model can show the characteristics of the compound dampers well; compound dampers can effectively reduce the inter story drift, base reaction and damage of the structure; when the value of alternative stiffness ratio is 0.4,the better damping effect of the structure can be obtained.

Key words: compound dampers, equivalent model, coupling beams, seismic performance
