Short-limb steel plate shear wall with replaceable energy dissipation components and construction method thereof

Abstract

The invention discloses a short-limb steel plate shear wall with replaceable energy dissipation components and a construction method thereof. A first cross beam and a second cross beam are fixed to a position between steel columns in the shear wall, shear wall bodies are to a position fixed between the first cross beam and the second cross beam, the supporting plates and the rib plates in each shear wall body are perpendicular to the lower end faces and the upper end faces of the cross beams, the two sides of the supporting plates make contact with the rib plates, the rib plates are perpendicular to the width direction of the supporting plates, gaps are reserved between the rib plates and the steel columns, the shear wall bodies are arranged at intervals, the centers of first connecting plates are in cross contact and then fixed to form a first energy dissipation component, the two ends are fixed between the steel columns and the rib plates, and the shear wall bodies are fixed through second connecting plates, the first cross beam, the supporting plates, the rib plates and the second cross beam are made of steel, and the first connecting plates and the second connecting plates are made of low-yield-point steel. During construction, after the steel columns are fixed as required, the first cross beam and the second cross beam are fixed to the position between the two steel columns, recycled concrete is poured into the steel columns and the cross beams, and subsequent installation is completed after the recycled concrete forms required strength.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a short-leg steel plate shear wall with replaceable energy-consuming components and a construction method thereof. Background technique [0002] In recent years, with the rapid development of the construction industry, there are various forms of building structures, but there are some problems in the current building structures. [0003] The current frame structure has significant stress concentration at the nodes, low lateral stiffness, and is a flexible structure. Under strong earthquakes, the frame structure produces a large horizontal displacement, which is likely to cause serious structural damage. The current reinforced concrete shear wall structure has a large self-weight, high lateral stiffness, short natural vibration period of the structure, and poor ductility, which is not conducive to earthquake resistance. In addition, due to the continuous acceleration ...

AI Technical Summary

Problems solved by technology

[0003] The current frame structure has significant node stress concentration and small lateral stiffness, which is a flexible structure. The frame structure has a large horizontal displacement under the action of strong earthquakes, which is likely to cause serious structural damage.

The current reinforced concrete shear wall structure has a large self-weight, large lateral stiffness, short natural vibration period of the structure, and poor ductility, which is not conducive to earthquake resistance.

In addition, due to the continuous acceleration of building renewal, a large number of old urban residential areas have been demolished, resulting in a huge amount of waste concrete, which seriously pollutes the ecological environment and occupies valuable land resources.
