Modern steel structure building systems often adopt a supporting structure or a shear wall structure, and the shear wall structure system mostly uses a steel plate shear wall composed of embedded steel plates, steel beams and steel columns. Compared with the traditional concrete structure wall, the wall has the advantages of light weight, high strength and shorter construction period, but simultaneously has the problem that the wall cannot be ignored:
1. embedded wallboard is the sheet metal basically in traditional steel sheet shear wall structure, and the easy outer bulging of taking place warp, is along with trembling and noise.
2. In application of the steel plate shear wall structure system, a buckling restrained component embedded with a wall plate, such as a concrete plate, a steel structure restrained component and the like, is often added to form a buckling-restrained steel plate shear wall structure. The buckling constraint component has large self weight, is difficult to install manually, has large construction difficulty, and can exert additional inertia force on the structure in an earthquake.
3. The buckling restrained members in the buckling-restrained steel plate shear wall structure system do not directly participate in structural stress, the material utilization rate is not high, the noise elimination function is not considered in the design, and certain noise can be caused in a normal use state.

Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments, and are not intended to limit the scope of the present disclosure. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, shall fall within the protection scope of the present invention.
There is shown in the drawings a schematic structural diagram in accordance with a disclosed embodiment of the invention. The figures are not drawn to scale, wherein certain details are exaggerated and possibly omitted for clarity of presentation. The shapes of various regions, layers and their relative sizes and positional relationships shown in the drawings are merely exemplary, and deviations may occur in practice due to manufacturing tolerances or technical limitations, and a person skilled in the art may additionally design regions/layers having different shapes, sizes, relative positions, according to actual needs.
Referring to fig. 1 and 2, the shear wall of the invention, in which the lightweight sandwich combined steel plate is embedded in the corrugated plates of the vertically arranged FRP profiles, comprises a shear wall body and a corrugated plate 1 of the FRP profiles; the FRP profile corrugated plate 1 is vertically placed at two sides of an embedded steel plate 3 in the shear wall body, and PET structural foam 2 is filled between the FRP profile corrugated plate 1 and the embedded steel plate 3;
the FRP section corrugated plate 1 and the embedded steel plate 3 are fixedly connected through the high-strength bolt 4 and the cross-section bonding agent to form a combined wall body, wherein a circular gasket is arranged between a nut of the high-strength bolt 4 and the FRP section corrugated plate 1. Be connected through fishplate 6 and bolt 5 between the girder steel 8 in FRP section buckled plate 1 and the shear force wall, wherein, fishplate 6 welds on girder steel 8, and fishplate 6 is connected with FRP section buckled plate 1 through bolt 5.
The PET structural foam 2 is used as a filling material, other light filling materials can be used as a substitute, and the section of the PET structural foam 2 is trapezoidal and is consistent with the wave trough shape of the side, facing the embedded steel plate 3, of the FRP section corrugated plate 1.
The construction process of the invention is as follows:
adhering PET structural foam 2 and FRP section corrugated plates 1 on an embedded steel plate 3 through an interface adhesive, and installing high-strength bolts 4 with round gaskets after punching to form a combined wall body; welding fishplate 6 on girder steel 8 afterwards, being connected FRP section bar buckled plate 1 and fishplate 6 through bolt 5, can accomplish the construction of wall body.
It should be noted that the present invention has the following features:
1) the combined section formed by the FRP section corrugated plates 1 and the PET structural foam 2 on the two sides of the embedded steel plate 3 can obviously improve the out-of-plane bending rigidity of the embedded steel plate 3, effectively limit the out-of-plane shearing buckling deformation of the embedded steel plate 3 and further improve the lateral rigidity resistance of the whole structure.
2) According to the invention, the FRP section corrugated plate 1 extends vertically and is fixed with the steel beam 8 through the high-strength bolt 4, so that the FRP section corrugated plate 1 can directly participate in bearing the horizontal load of the shear wall. Meanwhile, the FRP section corrugated plate 1 is only connected with the steel beam 8, so that an additional bending moment effect cannot be transferred to the frame column, and the additional bending moment effect of the FRP section corrugated plate 1 on the steel beam 8 can be mutually offset with the corresponding bending moment effect of the upper wallboard, so that the force transfer path of the FRP section corrugated plate 1 is clear, and the design requirement of surrounding frame members cannot be improved.
3) According to the invention, the FRP section corrugated plate 1 controls the plane external rigidity distribution of the FRP section corrugated plate 1 through the arrangement of the wave trough and wave crest widths, so that the local buckling deformation of the wallboard is concentrated at the wave trough position of the PET structural foam 2, and further, the energy absorption and noise elimination effects are achieved through the elastic deformation of the PET structural foam 2.
4) The composite sandwich panel composed of the FRP section corrugated plate 1, the PET structural foam 2 and the embedded steel plate 3 has higher integral bending rigidity and torsional rigidity, can still exert enough horizontal shear-resisting bearing capacity even if only connected with the steel beam 8, and can be flexibly arranged according to the sizes of the steel beam 8 and the steel column 7 in practical application.
