Shear yield type buckling restrained brace
The invention belongs to the technical field of earthquake resistance and shock absorption of civil engineering, and particularly relates to a shear yield type buckling restrained brace. Comprising a buckling restrained brace part, a shear yield damper part, a limiting device and a connecting part, the buckling restrained brace part and the shear yield damper part are connected in series through the connecting part, and the limiting device is arranged between the shear yield damper part and the connecting part; by combining the shear type metal damper and the buckling restrained brace, the defect of small-earthquake elasticity of a conventional buckling restrained brace is overcome, meanwhile, the buckling restrained brace is improved compared with the conventional buckling restrained brace structure, and the energy consumption effect of the buckling restrained brace is improved. Therefore, the combined shear yield type buckling restrained brace has the mechanical characteristics of small yield displacement and high ductility ratio, and the design goal that energy can be consumed in small earthquakes, medium earthquakes and large earthquakes can be achieved.
本发明属于土木工程抗震与减震技术领域，具体涉及一种剪切屈服型屈曲约束支撑；包括约束耗能支撑部分，剪切屈服型阻尼器部分、限位装置和连接部，屈曲约束支撑部分和剪切屈服型阻尼器部分通过连接部串联设置，限位装置设置在剪切屈服型阻尼器部分和连接部之间；通过结合剪切型金属阻尼器和屈曲约束支撑，解决了常规屈曲约束支撑小震弹性的缺陷，同时，本发明所用屈曲约束支撑较常规屈曲约束支撑结构有所改进，提高了屈曲约束支撑的耗能效果。因此，本发明一种组合式剪切屈服型屈曲约束支撑具有小屈服位移高延性比力学特性，可实现小震、中震和大震均可耗能的设计目标。
