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.
