Anti-buckling steel plate shear wall with combined vertical seams

Abstract

The invention discloses an anti-buckling steel plate shear wall with combined vertical seams. The anti-buckling steel plate shear wall comprises a plurality of layers of low-yield point steel plates, and a plurality of groups of vertical seams in different lengths are formed in each of the steel plates. The anti-buckling steel plate shear wall further comprises a constraint component, and the lower part of each of the steel plates is inserted in the constraint component; an antifriction layer is arranged on the surface of each of the steel plates, a cushion block continuously arranged in the horizontal direction is arranged between each of the upper end and the lower end of each of the steel plates and the adjacent steel plate or the constraint component, and the part between each of the steel plates and the adjacent steel plate or the constraint component is filled with mortar; a connecting piece is arranged at each of the upper end and the lower end of the two sides of the shear wall, and connects and fixes the shear wall and a concrete frame beam through a fastening part. The anti-buckling steel plate shear wall disclosed by the invention has the benefits that by utilizing good plastic properties of the low-yield point steel plates, the anti-buckling steel plate shear wall with the structure has better energy dissipation capacity and ductility performance as compared with a traditional steel plate shear wall; by forming the vertical seams in different lengths in each of the low-yield point steel plates, a moderate and major earthquake multi-stage yielding energy dissipation mechanism can be formed, a weak link in the structure is formed, and the effect of a structure fuse is achieved.

Description

technical field [0001] The patent of the invention belongs to the field of structural engineering, and relates to the energy dissipation and shock absorption of a prefabricated concrete structure system, in particular to an anti-buckling steel plate shear wall with combined vertical joints. Background technique [0002] Since the United States, Canada and Japan applied steel plate shear walls to multi-story buildings in the 1970s, since the development of steel plate shear walls for 30 years, the experimental research and numerical analysis on it as the main horizontal lateral force system show that the steel plate shear The wall has the advantages of lateral stiffness, high bearing capacity, good ductility, and high safety reserve. The steel plate shear wall has become a very promising lateral force resisting system, and is gradually being used in high-intensity earthquake areas in my country. However, most of the steel plate shear walls that have been used in engineering ...

AI Technical Summary

Problems solved by technology

In addition, the existing steel plate shear walls with slots have the same length of vertical joints and high yield bearing capacity, which cannot realize multi-stage yield energy dissipation in moderate earthquakes and large earthquakes, and the dissipation capacity is not satisfactory. If there are no restraints on both sides, out-of-plane buckling will occur prematurely, resulting in serious damage to its lateral stiffness, bearing capacity, and ductility, failing to achieve the expected goal of good energy dissipation
