Along with the continuous development and progress of economic level, scientific level and building level, the building structure in China also presents a more and more complex development trend, the building height is increased day by day, and high-rise and super high-rise buildings are common in all big cities. Along with the increasing height of buildings, horizontal load gradually replaces vertical load to become an important control factor in the design of high-rise buildings, and the traditional lateral force resisting member cannot meet the requirements of the high-rise buildings on energy consumption capacity and horizontal bearing capacity.
The steel plate composite wall structure is a novel lateral force resistant structure system developed in the last 70 th century, and becomes a structure favored by many designers due to the extremely high bearing capacity, the stable energy consumption capacity and the good ductility. Over the past 40 years, experimental studies and numerical analysis on steel plate walls as the main horizontal lateral force resisting system revealed its unique performance, including large elastic initial stiffness, large deformability and good plasticity properties, stable hysteresis characteristics, etc. The steel plate wall becomes a high-rise lateral force resisting system with great development prospect, and is particularly suitable for buildings in high-intensity earthquake areas.
The double-layer steel plate and concrete filled combined wall is one of steel plate-concrete combined walls. In the combined wall, concrete is positioned at a core position and is restrained by two steel plates; meanwhile, the core concrete can also play a role in preventing the steel plate from buckling too early. From the aspect of stress performance, the combined mode can exert the advantages of two materials, has very high compression bearing capacity and shear bearing capacity, and is particularly suitable for high-rise and super high-rise buildings.
On the basis, in order to overcome the defect that the double-layer steel plate composite wall is prone to out-of-plane buckling, further enhance the bearing capacity and energy consumption capacity of the double-layer steel plate composite wall, improve the buckling mechanism of the double-layer steel plate composite wall, achieve the assembly of steel structure residential construction, and meanwhile, based on the idea of improving the elastic shear buckling load and the shear bearing capacity of the shear wall, the invention provides the double-layer steel plate composite shear wall formed by truss-type pulling of the corrugated web I-shaped steel member.

The corrugated web I-shaped steel member is welded in the steel plate outside the steel plate shear wall unit in the middle, and the central axis of the corrugated web I-shaped steel member is ensured to be superposed with the central axis of the steel plate shear wall unit.
The advantages of the patent are mainly shown in the following aspects:
1. in double-deck steel sheet shear force wall, the connection between the inside two-layer steel sheet is the difficult problem of solving always, and inside and marginal portion connected mode are unanimous effectively guaranteed through the steel sheet shear force wall unit that sets up area wave web I-shaped steel member to this patent, can not appear in the atress in-process because the local wall body that the weak area of connection leads to destroys, has effectively improved the whole bearing capacity of wall body.
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. In addition, besides the connection of outer steel plates, a plurality of tie bars which are obliquely arranged are arranged between the upper and lower corrugated web plate I-shaped steel members in the steel plate shear wall unit, so that a stable truss type steel plate shear wall unit is formed, the failure of the connection part of the internal members in the compression process of the steel plate shear wall is avoided, the bonding effect between the steel plate and the concrete can be effectively enhanced just because the contact surfaces of the corrugated web plate I-shaped steel members, the tie bars and the steel plate and the concrete are larger, and the integrity of the combined shear wall is improved.
3. The corrugated web H-shaped steel members in the adjacent steel plate shear wall units are arranged in the same way along the length direction of the outer steel plates, so that the buckling mechanism of the wall body is improved, the integral buckling of the wall body is changed into the partial buckling of partial wall body units, the possibility of integral instability of the wall body is reduced, and the integral bearing capacity of the wall body is enhanced.
4. As the connecting component, because the corrugated web plate can not transmit axial force, the corrugated web plate in the corrugated web plate I-shaped steel component 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 the 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 corrugated web plate I-shaped steel component 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 and the inner corrugated web I-shaped steel member interact with each other, so that the overall bearing capacity of the wall body is improved. On one hand, in the process of bearing pressure or shearing force, the two outer steel plates are easy to generate single-wave buckling instability, and the two outer steel plates are pulled and connected through the corrugated web plate I-shaped steel member, so that outward bulging deformation or 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 a multi-bending side stress resisting member, the effect similar to embedding steel ribs in a wall body is achieved, and the side stress resisting bearing capacity and the compression resisting 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.
8. This patent has very big partly work to accomplish in the factory in the work progress, very big shortening construction period, the error that probably appears in the effectual field construction of having avoided has still alleviateed the environmental pollution of job site simultaneously.
