Problems solved by technology

The setting of the chute on the shear wall changes the complex stress state of the steel plate under horizontal shear. The inclined bars between the slits dissipate energy through tension and compression, but their stress mechanisms are different under reciprocating loads, and the concrete slabs on both sides cannot Effectively limit the buckling of the steel plate under compression

Embodiment

[0035] Such as figure 1 , figure 2 , image 3 A steel plate shear wall with openings and oblique seams is shown. The steel plate shear wall includes a thin steel plate 1 and a pair of edge stiffeners 2 arranged side by side on both sides of the thin steel plate 1. Each diagonal of the thin steel plate 1 A pair of diagonal slits 3 are symmetrically opened on the line, and four triangular holes 4 are opened on the thin steel plate 1 , and each triangular hole 4 is located between two adjacent diagonal slits 3 .

[0036] Wherein, the thin steel plate 1 is square, and the diagonal slits 3 are provided on the diagonal along the length direction of the diagonal. The triangular hole 4 is an isosceles triangle. The isosceles triangle can choose a right-angled isosceles triangle (such as Figure 4 shown) or a non-right isosceles triangle (such as Figure 5 shown).

[0037] The triangular hole 4 includes a top corner vertex 401 and a pair of bottom corner vertices 402. Between th...

Abstract

The invention relates to a steel plate shear wall with holes and inclined slots, and application thereof. The steel plate shear wall comprises a thin steel plate and a pair of edge stiffening ribs parallelly arranged at two sides of the thin steel plate, wherein each diagonal of the thin steel plate is symmetrically provided with a pair of diagonal inclined slots; the thin steel plate is also provided with four triangular holes; and each triangular hole is located between two adjacent diagonal inclined slots. In use, the steel plate shear wall is connected with a framed girder. Compared with the prior art, the steel plate shear wall provided by the invention has the advantages of definite lateral load resistance mechanisms, capacity of withstanding reciprocating load, adjustable design parameters, superior ductility and energy-dissipating capacity, and the like; and the steel plate shear wall has simple overall structure, can be fully bolted with the framed girder, and is easy to construct and replace and widely applicable to multi-rise structures.

Description

technical field [0001] The invention belongs to the technical field of steel plate shear walls, and relates to a steel plate shear wall with openings and oblique seams and an application thereof. Background technique [0002] The steel plate shear wall structure is a lateral force-resistant structural system developed in the 1970s. According to its historical development sequence, it can be roughly divided into the following categories: non-stiffened thick steel plate shear wall, stiffened steel plate shear wall, Non-stiffened thin steel plate shear wall, steel plate shear wall with slots on both sides, low yield point steel plate shear wall, open hole steel plate shear wall, profiled steel plate shear wall, vertical seam steel plate shear wall, combined steel plate shear Force wall, anti-buckling steel plate shear wall, anti-buckling open chute steel plate shear wall, etc. Among them, the representative ones are non-stiffened thin steel plate shear wall, vertical seam stee...
