Fabricated steel plate shear wall

Abstract

The present invention relates to a prefabricated steel plate shear wall, which includes frame columns 4 and frame beams 5 fixedly connected to each other, a plurality of embedded angle steels 1 and two horizontal edge members 2, and each frame column 4 is at the upper and lower parts Steel column sleeves 3 are fixedly connected; both ends of a horizontal edge member 2 are fixedly connected to two steel column sleeves 3 located on the upper parts of two frame columns 4 through high-strength bolts; the two ends of the other horizontal edge member 2 are respectively It is fixedly connected with two steel column sleeves 3 located at the lower part of the two frame columns 4 through high-strength bolts; each embedded angle steel 1 is obliquely fixed to two horizontal edge members 2 through friction-type high-strength bolts.

Description

technical field [0001] The invention relates to a novel assembled steel plate shear wall, which belongs to the technical field of structural engineering. Background technique [0002] The steel plate shear wall structure is a new type of lateral force-resisting structural system developed in the 1970s. The steel plate wall unit is composed of embedded steel plates, vertical edge members (columns or vertical stiffeners), and horizontal edge members (beams or horizontal stiffeners). When the steel plates are arranged continuously from top to bottom along a certain span of the structure, the steel plate shear wall system is formed. The overall mechanical characteristics of the steel plate wall are similar to the vertical cantilever composite beam fixed at the bottom: the vertical edge member is equivalent to the flange, the embedded steel plate is equivalent to the web, and the horizontal edge member can be approximately equivalent to the transverse stiffener . Compared with...

Problems solved by technology

[0004] Traditional thick steel plate shear walls generally do not undergo local buckling, and even if buckling occurs, no large tension bands will be formed. Due to the high steel consumption and high cost, its development is limited; , when the lateral force is small, local buckling will occur, and as the lateral force increases, tension bands will be formed on both sides of the steel plate. In order to ensure that the steel plate tension band fully functions, the surrounding members of the thin steel plate shear wall need to be properly strengthened , the buckling of the thin steel plate shear wall will affect the normal use of the wall, and will cause unsafe psychological effects on users; the traditional shear wall construction is complicated and cumbersome, and it is difficult to repair after the steel plate buckles
