Embodiment Construction

[0023] Figure 1 to Figure 3 Shown is the first embodiment of the buckling-constrained stiffened steel plate shear wall of the present invention.

[0024] The buckling-constrained stiffened steel plate shear wall includes an embedded steel plate 1 , a reinforced concrete cover plate 2 , edge members, and eight vertical stiffened ribs 5 . The edge member includes an edge beam 3 and an edge column 4 , and the embedded steel plate 1 is fixedly connected with the upper and lower edge beams 3 , and the embedded steel plate 1 can also be fixedly connected with at least one edge column 4 at the same time. The vertical stiffeners 5 are symmetrically fixed on both sides of the embedded steel plate 1, that is, each side of the embedded steel plate 1 is provided with four vertical stiffeners 5, and each reinforced concrete cover plate 2 is fixed on the same side and adjacent to each other. On the embedded steel plate 1 between the two vertical stiffeners 5. The embedded steel plate 1 i...

Abstract

The invention discloses a buckling-restrained stiffened steel plate shear wall and belongs to the technical field of structural engineering. The buckling-restrained stiffened steel plate shear wall comprises an embedded steel plate, reinforced concrete cover plates, an edge component, and stiffeners. The edge component comprises edge beams and edge posts. The embedded steel plate is fixedly connected with the upper and lower edge beams. The stiffeners are fixed on two sides of the embedded steel plate. The reinforced concrete cover plates are symmetrically fixed on two sides of the embedded steel plate. Gaps are reserved between each of the reinforced concrete cover plates and each of the embedded steel plate and the edge beams. The buckling-restrained stiffened steel plate shear wall effectively prevents buckling noise like 'drumbeat' and has better 'pinching' of hysteretic curves.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a novel lateral-force buckling-restrained stiffened steel plate shear wall that effectively prevents the buckling sound similar to "drumming" and improves the "pinching" phenomenon of the hysteretic curve. Background technique [0002] Steel plate shear wall is a new type of lateral force resistance structure developed in the 1970s. It has the characteristics of good ductility, large lateral stiffness of the structure, good ductility of components, and excellent seismic performance. In developed countries such as the United States and Japan, it has taken the lead in applying it to practical projects. In recent years, it has also begun to be used in high-intensity areas in my country, such as: Tianjin Tower in Tianjin, Shanghai Jinjiang Hotel and Tianjin International Finance Conference Hotel. Compared with concrete shear walls, steel plate shear walls have the foll...
