Self-resetting friction shock insulation support
The invention discloses a self-resetting friction shock insulation support which comprises a bearing plate A, a bearing plate B, a movable end plate, an SMA screw and a friction core column and has good vertical compression resistance and tension resistance. Under the simultaneous action of vertical and horizontal loads, friction force is generated between the core column friction surfaces of the friction core columns and the supporting plate, and energy is consumed; the horizontal displacement of the friction core column drives the movable end plate to move, so that the SMA screw rod on which the design prestress is applied is stretched, the design prestress not only provides a part of initial bearing force, but also promotes the friction core column to restore to the initial position after the horizontal load is removed, and a good self-resetting function is achieved. Particularly, the friction coefficient can be designed to be a constant friction coefficient or a variable friction coefficient, different energy dissipation capacities are provided, and the multi-target cooperative damping control requirements of the engineering structure in multiple aspects such as the bearing capacity, the energy dissipation capacity and the reset capacity can be met.
本发明公开了一种自复位摩擦隔震支座，包括：支承板A、支承板B、可移动端板、SMA螺杆、摩擦芯柱，具有良好的竖向抗压和抗拉能力。在竖向和水平荷载同时作用下，摩擦芯柱的芯柱摩擦面分别与支承板之间产生摩擦力并耗能；摩擦芯柱的水平位移带动可移动端板运动，从而拉伸施加了设计预应力的SMA螺杆，该设计预应力不仅提供一部分初始承载力，且在水平荷载去除后促使摩擦芯柱恢复到初始位置，实现良好的自复位功能。特别地，摩擦系数可设计为常摩擦系数或变摩擦系数，提供不同的耗能能力，可实现工程结构在承载能力、耗能能力和复位能力等多方面的多目标协同减震控制需求。
