The invention relates to the technical field of bridge engineering, in particular to a damping support with high loading capacity and transverse negative stiffness effect, which is connected with a bridge superstructure and a bridge substructure and comprises a top plate, a bottom plate, a spring and a support body. The top plate and the bottom plate are respectively connected with the bridge superstructure and the bridge substructure; a support body is arranged on the bottom plate; the support body comprises a support top plate, a support bottom plate and an energy consumption body; the energy consumption body is arranged between the support top plate and the support bottom plate, and the support bottom plate is connected with the bottom plate; a guide hole is formed in the support top plate, a guide rod is arranged on the top plate, and the guide rod penetrates through the guide hole to be movably connected with the support top plate. And a plurality of symmetrically distributed springs are arranged between the bottom plate and the top plate. According to the damping support, vertical bearing force is provided through the springs, vertical force borne by the support body is reduced, and the applicability of the support to a large-span bridge is improved; the springs achieve the negative stiffness effect when the support top plate and the support bottom plate make relative transverse movement, and the energy dissipation and shock absorption performance of a traditional support is greatly improved.
本发明涉及桥梁工程技术领域，尤其是涉及一种具有高承压能力和横向负刚度效应的减震支座，与桥梁上部结构和桥梁下部结构相连接，包括顶板、底板、弹簧和支座本体；顶板和底板分别与桥梁上部结构和桥梁下部结构相连接；底板上设置有支座本体；支座本体包括支座顶板、支座底板和耗能体；耗能体设置于支座顶板和支座底板中间，支座底板与底板相连接；支座顶板上设置有导孔，顶板上设置有导向杆，导向杆穿过导孔与支座顶板活动连接；底板和顶板之间设置有若干对称分布的弹簧。本发明的减震支座，通过弹簧提供竖向支承力，减少支座本体受到的竖向力，提升了支座对大跨桥梁的适用性；弹簧在支座顶板与支座底板发生相对横向运动时实现负刚度效果，极大提升传统支座的耗能减震性能。
