Anti-buckling friction damper
The invention relates to the technical field of earthquake resistance and disaster prevention of building structures, in particular to an anti-buckling friction damper. The buckling-restrained friction damper comprises a buckling-restrained energy dissipation section located in the middle, and self-resetting friction energy dissipation sections located at the two ends of the buckling-restrained energy dissipation section. The buckling-restrained energy dissipation section comprises a core steel pipe, steel column bodies are connected to the two ends of the core steel pipe, and the core steel pipe is surrounded by two semicircular pipes to form a sleeve. The two semicircular pipes are connected with steel plates corresponding in position in the pipe direction, the steel plates on the two sides are connected through bolts, and a friction pad is further arranged between the steel plates on the two sides. The self-resetting friction energy dissipation section comprises an inner friction plate, one end of the inner friction plate is connected with the steel column body, the number of the outer friction plates is two, the outer friction plate, the inner friction plate and the other outer friction plate are sequentially connected through a disc spring bolt, and the outer friction plate, a clamping plate and the other outer friction plate are sequentially connected through a disc spring bolt. The damper has no residual deformation under small and medium earthquakes, and the stability of the buckling-restrained brace and the overall energy-dissipating capacity of the component during yield energy dissipation are improved under large earthquakes.
本发明涉及建筑结构抗震防灾技术领域，尤其是涉及一种防屈曲摩擦阻尼器。该防屈曲摩擦阻尼器包括防屈曲耗能段位于中间，自复位摩擦耗能段位于防屈曲耗能段的两端；防屈曲耗能段包括核心钢管两端均连接有钢柱体，两根半圆形管将核心钢管包围形成套筒；两根半圆形管沿管方向连接有位置对应的钢板，两侧钢板通过螺栓连接，两侧钢板之间还设置有摩擦垫；自复位摩擦耗能段包括内摩擦板一端与钢柱体连接，外摩擦板设置有两个，通过含碟簧螺栓将外摩擦板、内摩擦板和另一个外摩擦板依次连接，通过含碟簧螺栓将外摩擦板、夹持板和另一个外摩擦板依次连接。小、中震下阻尼器没有残余变形，大震下增加屈服耗能时防屈曲约束支撑的稳定性和构件整体耗能能力。
