[0011] Specific implementation mode two: combination Figure 3-Figure 6 Explain that the steel-concrete composite shear wall stiffened by steel trusses in this embodiment also includes a second stiffened steel body B; the second stiffened steel body B has the same structure as the first stiffened steel body A, and the two A pair of thick sides of a steel plate 3 along the vertical direction are connected to the second reinforcement member 5, and a plurality of shear connection keys 7 in the second reinforcement member 5 are located between the two steel plates 3 in the second stiffened steel body B; The concrete 6 is poured in the second stiffened steel body B, and the first stiffened steel body A and the second stiffened steel body B are connected to form a -shaped or L-shaped or T-shaped or cross-shaped structure.

[0012] This embodiment adopts a second stiffened steel body B, the structure of the second stiffened steel body B is the same as that of the first stiffened stee...

specific Embodiment approach 3

[0017] Specific implementation mode three: combination image 3 and Figure 4 To illustrate, the erection bars 1-2 of this embodiment are corrugated bars or trapezoidal bars. Such setting can improve the stable bearing capacity of the steel plate and prevent premature local buckling of the steel plate during construction and use. At the same time, the steel truss can ensure that the internal concrete and the steel plate work together as a whole. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a steel bar truss stiffened steel concrete composite shear wall, relates to a shear wall and belongs to the field of building structures. The steel bar truss stiffened steel concrete composite shear wall aims to solve the problems that an existing steel concrete shear wall is poor in anti-seismic property, prone to crack and complex in construction when connected with steel members. The steel bar truss stiffened steel concrete composite shear wall comprises a second stiffening member, concrete, a first stiffened steel body and a plurality of shearing-resistant connecting keys. The first stiffened steel body comprises a first stiffening member, two steel plates, a plurality of transverse steel bars and a plurality of steel bar trusses. Each steel bar truss comprises two erection steel bars and three longitudinal steel bars, wherein the three longitudinal steel bars are arranged in a triangular shape, and the steel bar trusses are arranged in parallel between the two steel plates in the horizontal direction. The erection steel bars are connected to the steel plates. The transverse steel bars are horizontally arranged between the two steel plates, and the transverse steel bars are connected with the steel bar trusses. The first stiffening member and the second stiffening member are provided with the shearing-resistant connecting keys, and the concrete is poured on the first stiffening steel body and the second stiffening member.

Description

technical field [0001] The invention relates to a shear wall and belongs to the field of building structures. Background technique [0002] Shear wall is a kind of lateral force component commonly used in high-rise buildings. It is widely used in high-rise building structures, especially reinforced concrete shear walls are characterized by good integrity, high rigidity, small lateral deformation, resistance to wind loads and medium and small It has the advantages of good earthquake effect and fire resistance, and is widely used in practical engineering. However, the reinforced concrete shear wall has a large structural rigidity and bears a large horizontal force under the action of earthquakes. The cracks occur earlier, and the shear failure is mainly in the later period. The ductility and energy dissipation capacity are poor, and the failure is brittle. At the same time, the reinforced concrete shear wall is self-heavy, which leads to an increase in seismic load, structure...
