Anti-buckling steel plate shear wall with end columns and its construction method

Abstract

The invention relates to a buckling-proof steel plate shear wall with end columns and construction method thereof. The buckling-proof steel plate shear wall comprises a steel structural framework consisting of a left upright column, a right upright column, an upper cross beam and a lower cross beam, wherein a buckling-proof steel plate wall connected with the upper cross beam and the lower cross beam is arranged inside the steel structural framework; the buckling-proof steel plate wall consists of an embedded steel plate in the middle and reinforced concrete cover plates on the two sides; the upper side and the lower side of the embedded steel plate are connected with the upper cross beam and the lower cross beam through an upper fish plate and a lower fish plate respectively; the two sides of the embedded steel plate are connected with a left end column and a right end column through a left fish plate and a right fish plate respectively; column connecting keys and connecting plates are arranged at the upper and lower ends of the end columns respectively; beam connecting keys are arranged on the left and right sides of the bottom side of the upper cross beam respectively; the column connecting keys at the upper ends of the left end column and the right end column are connected with the beam connecting keys of the upper cross beam through bolts respectively; the connecting plates at the lower ends of the left end column and the right end column are connected with the lower cross beam respectively. According to the invention, a stable boundary condition is provided for the steel plate shear wall, and the load-bearing performance and the energy-dissipating capacity of the steel plate shear wall are improved.

Description

technical field [0001] The invention relates to a shear wall member which is particularly suitable for high-intensity fortification earthquake areas and is convenient for opening openings, and particularly relates to a buckling-resistant steel plate shear wall with end columns and a construction method thereof, which is applied in the field of structural engineering. Background technique [0002] The steel plate shear wall is a new type of lateral force-resistant member for building structures developed in the 1970s. It has the advantages of high initial stiffness, high bearing capacity and good ductility, and is especially suitable for earthquake-resistant buildings in high-intensity areas. Compared with thick steel plate shear walls, thin steel plate shear walls are more economical and have broad application prospects. However, because the steel plate is thin, it is easy to buckle early, resulting in a decrease in its stiffness and energy dissipation capacity. A reinforce...

AI Technical Summary

Problems solved by technology

The rationally designed four-sided buckling-resistant shear wall has superior performance, but it needs to be collapsed and arranged, which is not conducive to the opening of doors, windows, and aisles; the shear wall connected on both sides is easy to open openings, but the test found that the two vertical sides are prone to buckling and the corners are relatively tight. Tearing occurs early, and its energy consumption and bearing capacity cannot be fully utilized
