Steel-timber composite shear wall with layered steel plates and timber cover plates
A steel-timber composite shear wall with layered steel plates and timber cover plates is provided in the present disclosure, including a rubber layer, with a first thin low yield point (LYP) steel plate and a second thin structural steel plate respectively arranged on both sides of the rubber layer. A first timber cover plate and a second timber cover plate are respectively arranged outside the first thin LYP steel plate and the second thin structural steel plate. The steel plate and the timber cover plate are fixed through self-tapping screws. The grain of the first and second timber cover plates are arranged obliquely, and the oblique angles are determined based on height and width of the timber cover plate. Compared with the prior art, the shear wall has the advantages of environment friendliness, good buckling restraint performance, high lateral stiffness, multi-stage load resisting mechanism, and high prefabrication rate.
