Self-resetting energy dissipation laminated shear wall and construction method thereof
The invention relates to the technical field of building structures, in particular to a self-resetting energy-dissipation laminated shear wall and a construction method thereof, and the self-resetting energy-dissipation laminated shear wall comprises a laminated shear wall and a self-resetting energy-dissipation device mounted at a wall foot of the laminated shear wall; the self-resetting energy consumption device comprises a steel pipe, a concrete grouting material in the steel pipe and a shape memory alloy, the shape memory alloy is vertically arranged in the concrete grouting material, and the shape memory alloy and the concrete grouting material are not restrained in the vertical direction; under the action of pressure, only the concrete grouting material and the shape memory alloy are pressed; under the action of tensile force, the shape memory alloy is stretched to be lengthened, and the concrete grouting material is not subjected to the tensile force; through the self-resetting energy dissipation wall foot device and a rubber material, a wall column main body structure is protected against damage in an earthquake, residual deformation of the structure is reduced, and rapid recovery of the structure function after the earthquake is achieved.
本发明涉及建筑结构技术领域，特别涉及一种自复位耗能叠合剪力墙及其施工方法，包括叠合剪力墙和安装在所述叠合剪力墙墙脚的自复位耗能装置；所述自复位耗能装置包括钢管、钢管内部的混凝土灌浆料以及形状记忆合金，所述形状记忆合金竖直设置在所述混凝土灌浆料内且两者间无竖直方向约束；压力作用下，仅所述混凝土灌浆料和所述形状记忆合金受压；拉力作用下，所述形状记忆合金受拉伸长，所述混凝土灌浆料不受拉力；本发明通过自复位耗能墙脚装置和橡胶材料，保护墙肢主体结构在地震中免遭破坏，减小结构残余变形，实现震后结构功能的快速恢复。
