摘要
为研究消能摇摆架对钢筋混凝土(RC)框架结构的损伤控制作用及其应用于工程抗震加固的可行性,对一栋五层设计有消能摇摆架-框架的RC混凝土框架结构,与设计有屈曲约束支撑加固的消能减震结构、设计有摇摆墙加固的抗震结构和基础隔震结构进行抗震性能对比,通过分析在近场脉冲地震动、近场无脉冲地震动和远场地震动作用下各结构的位移、耗能情况,计算各结构的楼层损伤指数。分析结果表明:消能摇摆架能够有效抑制RC框架结构层间变形发展,减少结构耗能,降低RC框架结构的损伤,可用于结构的抗震加固。
In order to study the control ability of energy-dissipation light weight rocking frame（ EDLRF） to reinforced concrete（ RC） framework structure,and the feasibility of its application in the field of aseismic strengthening of engineering,a five stories reinforced concrete framework with EDLRF was designed. Its aseismic property was compared with that of frame structures with buckling-restrained brace frame（ BRBF）,rocking-wall structure and base-isolated structure. By respectively analyzing the structure displacement and energy consumption under the nearfiled ground motions with pulse,near-filed ground motions with non-pulse and far-filed ground motions,the stories damage indexes of all structure systems were achieved. The result showed that EDLRF could effectively control the floor deformation of RC framework structure,reduce energy consumption of main structure and lower the structure energy dissipation. So EDLRF could be used in aseismic retrofitting structures.
