摘　　要：目的对一个首层薄弱的4层钢框架结构进行消能减震设计,研究该减震结构在不同地震烈度下的地震响应以及阻尼器的性能.方法根据日本隔震结构协会(JSSI)编写的《被动减震结构设计·施工手册》中介绍的被动消能减震设计方法,使用带缝钢板阻尼器,基于该结构减震性能曲线进行减震设计,对该减震结构进行拟动力子结构试验.结果在小震、中震及大震下,该减震结构的最大层间位移计角在1/50以内,阻尼器不发生面外变形,也不产生裂缝,与结构共同抵抗侧力,保证结构不发生破坏.结论该减震结构具有良好的减震性能,所采用的带缝钢板阻尼墙能够发挥其滞回耗能性能,但在大震后面外失稳,需要提供足够的面外约束进一步提升其抗震性能.The purpose of this research is to design and retrofit a four-story steel frame building by metallic dampers,and to study the seismic performance of the damped structure and dampers.Based on the method of“Design and Construction Manual of Passive Controlled Structures”by Japanese Association of Isolated Structures(JSSI)the metallic damper is the wall-type damper with slits.A pseudo-dynamic substructure test was conducted.The test result shows that the maximum story drift angles of the damped structure are less than 1/50 under small,medium and large earthquakes.It can be concluded that the metallic wall damper with slits are able to play a stable hysteretic energy dissipation loop,while the out-of-plane buckling shall be further restrained.
