连梁阻尼器在剪力墙结构中的减震效果分析

Energy dissipation effect analysis of shear wall structure with coupling beam damper

地震作用下剪力墙结构中的连梁阻尼器能够有效的耗散地震作用,并且震后修复相对简单,具有较为广泛的应用前景,所以有必要分析连梁阻尼器在剪力墙结构中的减震效果。本文采用快速非线性分析方法对剪力墙结构中的连梁阻尼器减震效果分析,同时分析了连梁阻尼器布置位置对减震效果的影响。研究表明:地震作用下连梁阻尼器为结构提供附加阻尼并发挥耗能作用,有效降低了剪力墙结构的地震力和层间位移角,大震作用下连梁阻尼器耗能效果更为明显;综合减震效果及经济性,连梁阻尼器宜布置于剪力墙结构的中上部。

Coupling beam damper in shear wall structure can consume seismic energy under earthquake action, and it is easy to be repaired post-earthquake. Coupling beam damper will have a wide application prospect. Therefore, it is need to analysis seismic energy dissipation effects of coupling beam damper located on shear wall structure. In this paper, the shock absorption effect of shear wall structure with coupling beam damper is analyzed with fast nonlinear analysis method. Meantime, the layout location of coupling beam damper is studied. The results indicate that： the earthquake action and drift of shear wall structure can be effective decreased because of coupling beam damper energy dissipation action. The structure energy dissipation effect is obviously under server earthquake action relative to minor earthquake action. It is reasonable to layout coupling beam damper located middle-upper part of shear wall structure, which consider shock absorption effect and economy.
