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 damage control of RC frame structure and its feasibility for seismic strengthening of RC frame, a five-story RC frame with RC frame structure and design The structure of energy dissipation and cushioning supported by buckling restraint is designed. The anti-seismic performance of anti-seismic structure reinforced by rocker wall and base isolation structure is designed. By analyzing the effect of near-field pulse ground motion, near-field pulseless ground motion and far-field ground motion Under the displacement of each structure, energy consumption, calculate the structure of the floor damage index. The analysis results show that the energy dissipation rocker can effectively reduce the deformation of the RC frame structure, reduce the energy consumption of the RC frame structure and reduce the damage of the RC frame structure, and can be used for the seismic strengthening of the structure.
