Problems solved by technology

The steel plate shear wall can form a sufficient "tension field" without significantly reducing the lateral bearing capacity. The essence is to protect both sides of the shear wall without greatly reducing the lateral bearing capacity of the steel plate shear wall. Steel columns, but no improvement has been made to the effect of vertical loads on the stiffened steel plate shear walls during construction and use; in addition, the steel plate shear walls have not involved the specification parameters of the openings opened on the embedded thin steel plates , and this is precisely the key factor affecting the lateral bearing capacity of steel plate shear walls

Embodiment 1

[0024] Such as figure 1 As shown, the main structure in this embodiment includes top frame beam 1, bottom frame beam 2, left frame column 3, right frame column 4, embedded steel plate 5, stiffener 6, embedded steel plate 5 and top frame beam 1 and bottom The frame beam 2 is connected with the left and right frame columns 3 and 4, and the stiffener 6 is connected with the embedded steel plate 5 by welding or high-strength bolts.

[0025] The horizontal side of the embedded steel plate 5 includes the upper side and the lower side. In this embodiment, the upper side of the embedded steel plate 5 is provided with an upper arc-shaped incision 7, and the arc length L of the upper arc-shaped incision 7 is c is the horizontal direction, arc height H c for vertical.

Embodiment 2

[0027] This embodiment has been improved on the basis of Embodiment 1, such as figure 2 As shown, the difference is that in this embodiment, the lower side of the embedded steel plate 5 is also provided with a lower arc-shaped incision 8, and the two arc-shaped incisions (7, 8) correspond to the upper and lower sides, and are all located on the embedded steel plate. 5. At the middle position horizontally to the side, the lower arc-shaped incision 8 has the same size and parameter settings as the upper arc-shaped incision 7, and the arc length is L c is the horizontal direction, the arc height H c for vertical.

Abstract

The invention discloses an arc-shaped notch stiffened steel plate shear wall for reducing the influence of vertical loads. The wall comprises a main body structure composed of frame columns and framebeams; embedded steel plates are installed in the main body structure, stiffening ribs and the embedded steel plates are welded or connected through high-strength bolts, the embedded steel plates areconnected with the frame columns and the frame beams, arc-shaped notches are formed in the horizontal side edges of the embedded steel plates, the arc length of each arc-shaped notch is in the horizontal direction, the arc height of each arc-shaped notch is in the vertical direction, and the arc-shaped notches are located in the middles of the horizontal side edges of the embedded steel plates; the arc length of each arc-shaped notch is 1 / 3 to 1 / 4 of the span of the embedded steel plates, and the arc height range of each arc-shaped notch is 10-15 cm. By means of the wall, the lateral deformation resistance of the stiffened steel plate shear wall can be fully exerted, and the adverse influence of the vertical loads on the lateral deformation resistance of the steel plate shear wall is effectively reduced.

Description

technical field [0001] The invention relates to a steel plate shear wall, which belongs to the technical field of construction engineering, in particular to an arc-shaped notch-stiffened steel plate shear wall which reduces the influence of vertical loads. Background technique [0002] Steel plate shear walls are a new type of lateral force-resisting member developed in the 1970s. According to different structural forms, steel plate shear walls can be divided into five categories: non-stiffened steel plate shear walls, stiffened steel plate shear walls, buckling-resistant Steel plate shear wall, steel plate combined shear wall and slotted steel plate shear wall. Compared with reinforced concrete shear walls, steel plate shear walls are small in size, light in weight, increase the usable area of ​​the house, reduce foundation cost, and have good economic benefits. At the same time, they also have large lateral stiffness, high shear bearing capacity, and ductility Therefore, ...
