Multi-stage energy consumption self-resetting friction type damper
The invention discloses a multi-stage energy consumption self-resetting friction type damper which comprises a self-resetting module composed of a shape memory alloy bar and a baffle. The friction energy consumption module is composed of an inner pulling and pressing plate, a high-strength bolt, a friction plate, stainless steel, a belleville spring and channel steel; the limiting module is composed of a limiting plate and an external connecting device. According to the damper, different damping forces can be obtained by adjusting the pre-tightening force of the high-strength bolts and the types and the number of the friction plates, and different self-resetting capacities can be obtained by adjusting the types, the number and the diameters of the SMA bars. Through the self-resetting function, post-earthquake residual deformation of a structure or a component is reduced; the damper main body structure is prevented from generating overlarge plastic deformation and damage through friction energy consumption, and the time and cost required by normal function recovery of the structure after an earthquake are reduced; and through the combined action with different structural members, the performance design of the building structure is achieved, different performance targets are achieved, and then the requirements of the structure for different anti-seismic performance are met.
本发明公开了一种多阶段耗能自复位摩擦型阻尼器，包括形状记忆合金棒材和挡板组成的自复位模块；内拉压板、高强螺栓、摩擦片、不锈钢、碟形弹簧、槽钢组成的摩擦耗能模块；限位板和外部连接装置组成的限位模块。该阻尼器可通过调整高强螺栓预紧力、摩擦片的种类和数量来获得不同大小的阻尼力，通过调整SMA棒材的种类、数量和直径来获得不同大小的自复位能力。本发明通过自复位功能以减小结构或构件的震后残余变形；通过摩擦耗能避免阻尼器主体结构自身产生过大的塑性变形和损伤，降低震后结构正常功能恢复所需的时间和成本；与不同结构构件的联合作用，实现对建筑结构的性能化设计，达到不同的性能目标，进而满足结构对不同抗震性能的需求。
