The invention relates to an assembly type residential steel structure system. The system comprises steel plate shear walls, superimposed steel composite beams and superimposed floor stabs; stiffened plates are welded to the steel plate sheer walls; the end portions of the superimposed steel composite beams are connected with the steel plate shear walls; an out-wrapped concrete layer is wrapped on the outer surface of each superimposed steel composite beam, and stressed steel bars are laid in the out-wrapped concrete layer; the stressed bars are connected to the stiffened plates; the superimposed floor stabs are connected to the superimposed steel composite beams. The fabricated steel structural system of the house has the advantages of high industrialization and modularization, controllable quality and short investment payback period and can be applied and popularized in the field of architecture structures.

The invention relates to a fabricated shear resisting unit. The fabricated shear resisting unit is characterized by comprising an I-type shear resisting unit body and an II-type shear resisting unit body; the I-type shear resisting unit body comprises a first frame and two stiffeners, the hollowed-out first frame is defined by fixedly connecting a first upper frame part, a first lower frame part,a first left frame part and a first right frame part, and the two stiffeners are arranged in a crossed manner about the diagonal of the first frame; the II-type shear resisting unit body comprises a second frame, two steel channels and a reinforced steel channel, the hollowed-out second frame is defined by fixedly connecting a second upper frame part, a second lower frame part, a second left framepart and a second right frame part, the two steel channels are arranged in a crossed manner about the diagonal of the second frame, and the reinforced steel channel is arranged between two arbitrarysteel channels. The invention further discloses a wall. The shear resisting unit bodies both have good shear resisting capacity and bearing capacity and are all connected through bolts, welding construction is not needed on site, construction is easy, and the fabricated shear resisting unit can be flexibly assembled according to actual construction needs.
