Shearing type buckling-restrained energy dissipation brace

Abstract

The invention provides a shearing type buckling-restrained energy dissipation brace which has similar tension and compression stiffness, can be mounted and manufactured easily and conveniently, is low in manufacturing cost and comprises a core steel plate, two outer-layer steel plates and bolts. The two outer-layer steel plates are respectively placed on two sides of the core steel plate, mounting connecting sections and steel plate connecting sections are arranged at two ends of the core steel plate, an energy dissipation section is arranged in the middle of the core steel plate, open slots are formed in two ends of the energy dissipation section, deformation holes which are regularly arrayed are formed in positions between the open slots in the two ends of the energy dissipation section, core bolt holes are formed in the steel plate connecting sections, outer-layer bolt holes which are matched with the core bolt holes are formed in the outer-layer steel plates, and the bolts are connected with the core steel plate and the outer-layer steel plates by the core bolt holes and the outer-layer bolt holes. The shearing type buckling-restrained energy dissipation brace has the advantages that the deformation holes which are regularly arrayed are formed in the energy dissipation section of the core steel plate, so that energy can be dissipated, and the shearing type buckling-restrained energy dissipation brace has the similar tension and compression stiffness; the mounting connecting sections and the steel plate connecting sections are arranged at the two ends of the core steel plate, and accordingly the shearing type buckling-restrained energy dissipation brace can be manufactured and mounted conveniently.

Description

technical field [0001] The invention relates to a building structure component, in particular to a shear type anti-buckling energy dissipation support. Background technique [0002] Anti-buckling braces can provide great lateral stiffness and bearing capacity for frame or bent structures, and are widely used in various building structures. The common cross-sectional forms of buckling-resistant braces are one-shaped, cross-shaped, T-shaped, and double-T-shaped. There is a big difference between the tensile and compressive stiffness or bearing capacity; after the full section of the core element yields, the tensile or compressive stiffness of the support in the longer yield section is almost zero, which may cause problems such as accelerated movement of the connected structure. Most energy-dissipating braces are expensive or complex in structure, and the installation and manufacturing process is relatively cumbersome. Therefore, buckling-resistant braces are still a building ...

AI Technical Summary

Problems solved by technology

The structure of the anti-buckling support is complicated, and the installation and manufacture are not convenient enough, and there is also the problem that the entire anti-buckling support needs to be replaced after it is destroyed
