Large-displacement bridge self-resetting support and bridge structure
According to the large-displacement bridge self-resetting support and the bridge structure, an upper support body and a lower support body are both in sliding fit with sliding grooves through sliding blocks, elastic pieces are arranged at the two ends of each sliding block, combination of a friction pendulum type support structure and the elastic pieces is achieved, the structure provides a fixed sliding path for the upper sliding blocks and the lower sliding blocks, and the friction pendulum type support structure and the elastic pieces are combined; the combined action of the friction pendulum and the annular spring can greatly dissipate the earthquake acting force, meanwhile, the support has the large self-resetting capacity, and the earthquake acting force borne by the main beam and the bridge pier is reduced. The support can adapt to large fault dislocation displacement or pier-beam relative displacement, release internal force and effectively solve the problems that under the action of large fault dislocation displacement or strong near-fault earthquake, a support system loses efficacy and is damaged and a main beam falls down due to large displacement. A main beam and a cover beam of a bridge structure are connected through the large-displacement bridge self-resetting support, and the large-displacement bridge self-resetting support has high energy dissipation capacity and post-earthquake self-resetting capacity.
本发明公开一种大位移桥梁自复位支座及桥梁结构，上支座和下支座均采用滑块与滑槽滑动配合，且滑块两端均设置弹性件，实现了摩擦摆式支座结构与弹性件的联合，此结构不仅为上滑块、下滑块提供了固定滑动路径，而且摩擦摆和环形弹簧的共同作用可较大地耗散地震作用力，同时使支座有较大的自复位能力，减小主梁及桥墩所受的地震作用力。该支座可适应较大的断层错动位移或墩梁相对位移，释放内力，能有效解决在较大的断层错动位移或强近断层地震作用下支座系统因大位移而导致失效破坏及主梁落梁的问题。桥梁结构的主梁和盖梁之间通过上述的大位移桥梁自复位支座相连，具有较高的耗能能力和震后自复位能力。
