Beam column energy dissipation connecting piece based on U-shaped plate and construction method thereof
The invention discloses a beam column energy dissipation connecting piece based on a U-shaped plate and a construction method thereof. The beam column energy dissipation connecting piece comprises a column side end plate, the column side end plate and a beam side end plate are vertically arranged at a beam column joint in parallel, connecting profile steel is fixedly arranged between the column side end plate and the beam side end plate, and the beam side end plate is fixed to the beam end of a prefabricated beam through prestressed tendons; two energy dissipation units are symmetrically arranged on the upper and lower sides of the connecting profile steel, one end of each energy dissipation unit is fixedly connected with the column side end plate, and the other end of each energy dissipation unit is fixedly connected with the beam end of the prefabricated beam; and the column side connecting plate and the beam side connecting plate in the energy dissipation unit are vertically arranged in parallel and are fixedly connected with the column side end plate and the beam end of the prefabricated beam correspondingly, and a U-shaped plate is arranged between the column side connecting plate and the beam side connecting plate. Plastic deformation of the U-shaped plate is used for dissipating energy, and the vibration reduction effect is achieved through yield energy dissipation of the joint; and the beam side end plates are fixed to the prefabricated beams through the prestressed tendons, under the action of prestress, residual deformation can be reduced, and the anti-seismic performance of the structure is effectively improved.
本发明公开了一种基于U型板的梁柱耗能连接件及其施工方法，包括柱侧端板，柱侧端板与梁侧端板竖向平行设置在梁柱节点处，连接型钢固定设置在柱侧端板与梁侧端板之间，梁侧端板通过预应力筋与预制梁的梁端固定；两个耗能单元对称设置在连接型钢的上下两侧，耗能单元的一端与柱侧端板固定连接，另一端与预制梁的梁端固定连接；耗能单元中的柱侧连接板与梁侧连接板竖向平行设置，并分别与柱侧端板及预制梁的梁端固定连接，U型板设置在柱侧连接板与梁侧连接板之间；本发明利用U型板的塑性变形进行耗能，通过节点的屈服耗能，起到减振的效果；梁侧端板通过预应力筋与预制梁固定，在预应力的作用下，能够减少残余变形，有效提高了结构的抗震性能。
