Trigger type limited negative stiffness high-strength spring damping support
The invention provides a trigger type limited negative stiffness high-strength spring damping support. The trigger type limited negative stiffness high-strength spring damping support comprises an upper connecting steel plate, a support upper-layer structure, supporting columns, a spring combination, a rubber support layer and a lower connecting steel plate. The support upper-layer structure is arranged at the top end of the upper connecting steel plate; and the supporting columns are perpendicularly hinged to the upper connecting steel plate and the lower connecting steel plate, the rubber layer support is installed between the upper connecting steel plate and the lower connecting steel plate, and the spring combination is perpendicularly anchored to the upper connecting steel plate and the lower connecting steel plate and hinged to the upper connecting steel plate and the lower connecting steel plate to form a ''K-shaped'' combined component. The damping support has beneficial effects that an enough bearing force is provided when an earthquake magnitude is low, negative stiffness performance is triggered when the earthquake magnitude is large, the negative stiffness and a commonpositive stiffness shock insulation support are combined in parallel, a total hysteretic curve is full, a shock insulation layer has a large damping ratio, a displacement response of structural vibration is effectively reduced, and an ideal shock insulation effect is achieved.
本发明提供了一种触发式有限负刚度高强弹簧减震支座，该触发式有限负刚度高强弹簧减震支座包括：上连接钢板、支座上层结构、支撑柱、弹簧组合、橡胶支座层和下连接钢板；在上连接钢板顶端设置有支座上层结构，若干支撑柱垂直铰接于上连接钢板和下连接钢板，在上连接钢板和下连接钢板之间安装有橡胶层支座，弹簧组合垂直锚固于上连接钢板和下连接钢板，并铰接于上连接钢板和下连接钢板，形成“K”字型组合构件。本发明的有益效果是：在震级较低时提供足够的承载力，在震级较大时触发负刚度性能，负刚度与普通正刚度隔震支座并联组合，总滞回曲线较饱满，使得隔震层具有较大的阻尼比、结构振动的位移响应有效减小，获得较为理想的隔震效果。
