Middle-bolted slit steel plate shear wall and processing and manufacturing method thereof

Abstract

The invention discloses a middle-bolted slit steel plate shear wall and a processing and manufacturing method thereof. The slit steel plate shear wall comprises two vertical slit steel plates and two T-shaped splints, wherein the longitudinal edge of each vertical slit steel plate is provided with a profile steel stiffener; the two vertical slit steel plates are arranged one above the other; a gap for adjusting a vertical installation error is formed between the two vertical slit steel plates; and two T-shaped splints are connected with the two vertical slit steel plates which are arranged one above the other through bolts. A high-intensity bolt connection position of a slit steel plate wall is moved to a middle region in which overturning moment is reduced greatly and the slit steel plate wall is connected with upper and lower frame steel girders by welding, so that the problem of bolt slippage of the slit steel plate wall is solved to a great extent and the increase of a large number of construction expenses for preventing the bolt slippage is avoided. Due to the overcoming or delaying of the bolt slippage, great noise caused by slippage is avoided and the problem of corner instability of the slit steel plate shear wall caused by the slippage is avoided or relieved. Simultaneously, the T-shaped splints form stronger traverse stiffeners in the middle of the slit steel plate wall, so that anti-seismic performance is enhanced remarkably.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, in particular to a steel plate shear wall bolted with seams in the middle and a manufacturing method thereof. Background technique [0002] The concept of steel plate shear wall with slots was first proposed by Japanese scholars Toko Hitaka et al. in 2002. The basic principle is: open several vertical seams on the steel plate, so that the plate strips (also known as columnar parts) between the vertical seams work like small columns under bending, so that the deformation of the original non-slit steel plate mainly shears into a strip seam. Steel plate bending is the main deformation, which will greatly improve the deformation and energy dissipation capacity of the steel plate shear wall with slots. The steel plate shear wall with slots also has the advantages of adjustable stiffness (through the slotting parameters), flexible space layout (not connected with frame columns but only ...
