Double-steel-plate shear wall internally provided with replaceable inclined struts and construction method of double-steel-plate shear wall

Abstract

The invention discloses a double-steel-plate shear wall internally provided with replaceable inclined struts and a construction method of the double-steel-plate shear wall. The double-steel-plate shear wall internally provided with the replaceable inclined struts comprises a first steel plate, a second steel plate, first steel columns, second steel columns, connecting pieces, first steel pipes and second steel pipes, third steel pipes and fourth steel pipes, wherein the first steel plate and the second steel plate are fixed between two first steel columns, one sides of the second steel columns are fixed to one sides of the first steel columns, the other sides of the second steel columns are fixed to one sides, in the length direction, of the first steel plate and the second steel plate, and recycled concrete is poured into the first steel columns and the second steel columns; the connecting pieces are evenly and symmetrically fixed to the upper ends and the lower ends of the inner sides of the first steel plate and the second steel plate, each first steel pipe, each second steel pipe, each third steel pipe and each fourth steel pipe form an inclined strut unit and intersect at one point, the upper ends of each first steel pipe and each second steel pipes are fixed to the upper end of the first steel plate, and the lower ends of each first steel pipe and each second steel pipes are fixed to the lower end of the second steel plate; the upper ends of each third steel pipe and each fourth steel pipe are fixed to the upper end of the second steel plate, the lower ends of each third steel pipe and each fourth steel pipe are fixed to the lower end of the first steel plate, and of the multiple inclined strut units are fixedly connected between the first steel plate and the second steel plate.

Description

technical field [0001] The invention belongs to the technical field of building structures, in particular to a double-steel plate shear wall with replaceable diagonal braces inside and a construction method thereof. Background technique [0002] Shear wall is an important component of high-rise buildings, which can effectively bear vertical load and horizontal load, and has high strength, stiffness and seismic performance. [0003] The prefabricated reinforced concrete shear walls commonly used in my country are mainly composed of prefabricated parts and cast-in-place parts, which have the advantages of saving formwork, fast construction speed and good integrity of cast-in-place. Due to the complex structure of the seam connection, there are disadvantages such as insufficient strength, difficult installation, non-recoverable and uneconomical after the earthquake. [0004] The design of high-rise building structures should play a role in resisting horizontal loads such as win...

AI Technical Summary

Problems solved by technology

At present, steel plate shear walls have been widely used in multi-story steel structure buildings, but there are also shortcomings such as structural lag and low bearing capacity. For example, the connection between steel plate and surrounding steel is not strong enough, and the bearing capacity of the wall is not high enough. The corresponding deformation and energy dissipation are relatively poor
