2. The corrugated web I-shaped steel member is newly introduced into the double-layer steel plate shear wall, the web of the corrugated web I-shaped steel member and the outer steel plate directly participate in the shear wall anti-side, and meanwhile, the flange of the corrugated web I-shaped steel member plays an obvious tensile action on the outer steel plate, so that the elastic shear buckling load of the outer steel plate and the shear bearing capacity of the outer steel plate are effectively improved; therefore, the web width of the corrugated web I-shaped steel member can be obviously larger than the horizontal distance of the corrugated web I-shaped steel member in the design process, the elastic buckling loads of the plates among the cells are convenient to be close, and the economical efficiency of the steel plate shear wall is effectively improved.

As the connecting component, because the corrugated web plate can not transmit axial force, the corrugated web plate in the I-shaped steel component of the corrugated web plate only bears lateral force and basically does not bear vertical force in the stress process of the wall body, compared with a flat web plate, the corrugated web plate can not be unstable when being pressed, the connecting performance of the corrugated web plate and a flange when the wall body is pressed is effectively ensured, the flange is effectively tied by the corrugated web plate, the stability of the flange is enhanced, the connecting performance of the I-shaped steel component of the corrugated web plate and an outer steel plate is further ensured, and the overall stability of the structure is obviously improved; the shear-resistant buckling capacity of the corrugated web is higher than that of a flat web, the integral shear-resistant capacity of the wall is improved by adopting the I-shaped steel member of the corrugated web, the flange is better supported by the corrugated web, and the stability of the outer steel plate is further enhanced; meanwhile, the out-of-plane bending stiffness of the corrugated web plate is higher than that of the flat web plate, and the corrugated web plate can be made to be high and thin, so that the width of the shear wall unit is larger, and the number of the shear wall units and the welding workload can be effectively reduced.
5. The outer steel plate interacts with the inner corrugated web I-shaped steel member, so that the overall bearing capacity of the wall body is improved. On the one hand, in the process of bearing pressure or shearing force, the two outer steel plates are easy to bend and lose stability in a single wave mode, and the two outer steel plates are pulled and connected through the corrugated web plate I-shaped steel component, so that the outward bulging deformation or the inward buckling deformation of the steel plates can be limited. On the other hand, the corrugated web I-shaped steel members can also serve as core stress members, the outer steel plates play a role in connecting the corrugated web I-shaped steel members to form multiple bending side force resisting members, the effect similar to embedding steel ribs in a wall body is achieved, and the side bearing capacity and the compression bearing capacity of the wall body are improved. In addition, the buckling deformation of the outer steel plate towards the inner side can be simultaneously inhibited through the action of the concrete; on the other hand, the outer steel plate can inhibit the development of concrete cracks, and further improves the bearing capacity of the wall body.
6. The integrally poured concrete can improve the compression and shear bearing capacity of the steel plate composite wall, the filled concrete provides transverse support for the peripheral steel plate and can restrain buckling deformation of the outer side steel plate, meanwhile, the peripheral steel plate provides lateral restraint for the filled concrete to enable the filled concrete to be in a bidirectional compression state, the compression resistance of the concrete is improved, and development of concrete cracks is slowed down. The double-layer steel plate can be used as a concrete template, so that a formwork supporting procedure is omitted, the construction period is shortened, and the concrete is restrained by the steel plate and cannot fall down even being crushed.
7. Novel steel sheet shear force wall arrangement mode is more nimble, because the area of wall body is great, and traditional steel sheet wall uses the steel sheet size great, and no matter transport or installation all have a lot of inconveniences. The steel plate shear wall units are spliced into the integral wall body on site in the form of steel plate shear wall units, so that the requirements of different sizes and forms can be met.
