technical field

The utility model relates to the field of shear walls, in particular to an I-shaped steel plate shear wall with stiffening ribs and seams.

Background technique

The frame-shear wall structure has many advantages such as flexible layout, large space, and large lateral rigidity, and is widely used in multi-storey and high-rise structures. In the frame-shear wall structure, the commonly used forms are concrete shear wall, steel plate shear wall and so on. Concrete shear walls have high rigidity, but brittle failure will occur under strong earthquakes, resulting in structural damage; steel plate shear walls have the characteristics of high lateral force rigidity, high bearing capacity, and good seismic performance, but in terms of economy and consumption There is still room for improvement in terms of performance; the slotted steel plate shear wall has better ductility and energy dissipation performance than ordinary steel plate shear walls, but the out-of-plane stiffness is reduced by the slots, which is prone to plane failure. External instability restricts its engineering application.

The purpose of this utility model is to overcome the deficiencies in the prior art and provide a steel plate shear wall with I-shaped stiffening ribs and seams. This type of shear wall has good out-of-plane stiffness and stability, and improves The mechanical properties improve the deformation capacity and energy dissipation capacity, and at the same time have good economy and practicability, which is conducive to the popularization and application of steel plate shear walls.

The purpose of this utility model is achieved by the following technical solutions:

An I-shaped stiffener steel plate shear wall with slots, comprising steel plate shear walls with slots arranged at equal intervals, stiffeners welded to the steel plate shear walls are arranged on both sides of the slots, the Both ends of the stiffening rib protrude from the slit, and the thickness of the stiffening rib is greater than that of the steel plate shear wall.

The width of the stiffeners on both sides of the steel plate shear wall is larger than that of other stiffeners.

The width-to-thickness ratio of the steel plate shear wall between the slits is 8-12, and the height-to-width ratio is 4-6.

Compared with the prior art, the beneficial effects brought by the technical solution of the utility model are:

Stiffeners welded to the steel plate shear wall are arranged on both sides of the slit in the steel plate shear wall, and the steel plate shear wall between the stiffeners forms an I-shaped stiffener together, so that the steel plate shear force The out-of-plane stiffness and stability of the wall are greatly improved compared with ordinary steel plate shear walls with slots. This setting effectively improves the energy dissipation performance and lateral bearing capacity of the steel plate shear walls with slots. Uniform, and the coefficient of steel consumption is significantly lower than that of steel plate shear walls without stiffeners.
