Self-resetting concrete frame structure steel plate energy-consuming infill wall and assembly method thereof
The invention relates to the technical field of infill wall assembly, in particular to a self-resetting concrete frame structure steel plate energy-consuming infill wall and an assembly method thereof. The infill wall comprises a precast concrete beam, a precast concrete column, a masonry infill wall, energy-consuming steel plates, a beam-side fixed pressure plate and a column side fixed pressureplate, wherein the precast concrete beam is installed vertically on the top right side wall of the precast concrete column, both the precast concrete beam and the precast concrete column are internally reserved with prestressed tendon channels, and the two prestressed tendon channels are connected end to end front and back in the horizontal direction. The invention can concentrate the nonlinear deformation of the infill wall structure at the connection, maintain elasticity between the multiple main parts of the infill wall, and can realize the rapid recovery of structural functions after the earthquake as the rebound effect of the un-bonded prestressed tendons is adopted to minimize the residual structural deformation. At the same time, the energy-consuming steel plates are installed on both sides of the masonry infill wall, which enhances the energy consuming capacity of the infill wall structure, significantly improves the seismic performance, and controls the maximum deformed structure under the action of the earthquake.
本发明涉及填充墙装配技术领域，具体涉及一种自复位混凝土框架结构钢板耗能填充墙及其装配方法，包括预制混凝土梁、预制混凝土柱、砌体填充墙、耗能钢板、梁侧固定压板以及柱侧固定压板，预制混凝土梁垂直安装于预制混凝土柱的顶端右侧壁，预制混凝土梁与预制混凝土柱的内部均预留有预应力筋孔道，且两条预应力筋孔道在水平方向上前后首尾相连；本发明能将填充墙结构的非线性变形集中于连接处，填充墙的多个主体部分之间保持弹性，利用无粘结预应力筋的回弹作用，结构残余变形很小，可实现震后结构功能的迅速恢复；同时在砌体填充墙的两侧均设置有耗能钢板，增强了填充墙结构的耗能能力，明显改善了抗震性能，控制结构在地震作用下的最大变形。
