Split type energy-dissipation anti-seismic combined bridge pier cross beam
The invention relates to the field of bridge pier cross beams, in particular to a split type energy-dissipation anti-seismic combined bridge pier cross beam. The split type energy-dissipation anti-seismic combined bridge pier cross beam comprises a middle cross beam and end cross beams located at the two ends of the middle cross beam, wherein the cross sectional area of each end cross beam is smaller than that of the middle cross beam, the rigidity of each end cross beam is smaller than that of the middle cross beam, and the middle cross beam and the end cross beams are detachably matched; and the end cross beams are connected with a pier structure when the split type energy-dissipation anti-seismic combined bridge pier cross beam is in use. When an earthquake occurs, the two ends, which are connected with the bridge pier, of the cross beam are often seriously damaged parts, and the middle of the cross beam can still be used after the earthquake. Therefore, the end cross beams located at the two ends of the cross beam and the middle cross beam in the middle are designed to be of a detachable matching structure, only the damaged end cross beams need to be replaced, the middle cross beam is reserved for continuous use, and then the purpose of saving materials is achieved.
本发明涉及桥墩横梁领域，具体是涉及一种分体式耗能抗震组合型桥墩横梁。分体式耗能抗震组合型桥墩横梁包括中部横梁和位于中部横梁两端的端部横梁，所述端部横梁的横截面积小于中部横梁的横截面积，且端部横梁的刚度小于中部横梁的刚度，所述中部横梁与端部横梁构成可拆卸式配合；使用时，端部横梁与桥墩结构相连接。在发生地震时，横梁与桥墩相连接的两端往往是受损比较严重的部分，而中部在地震之后往往还可以继续使用。因此，本发明将位于横梁两端的端部横梁与中间的中部横梁设计成可拆卸式的配合结构，只需要更换破坏的端部横梁而保留中部横梁继续使用，从而达到节约材料的目的。
