I-shaped steel plate shear wall with built-in round steel reinforcement cages and externally-attached steel plate supports and manufacturing method

Abstract

The invention relates to a combined steel plate shear wall, in particular to an I-shaped steel plate shear wall with built-in round steel reinforcement cages and externally-attached steel plate supports and a manufacturing method. According to the I-shaped steel plate shear wall, the I-shaped section is applicable to the arrangement mode of a shear wall body in a building structure, the space between the inner sides of two steel plates is filled with concrete, buckling deformation of the steel plates can be effectively restrained, and the buckling strength of the steel plates is improved; due to the fact that the internal concrete is restrained by the steel plates on the two sides, cavity separating plates and the round steel reinforcement cages in a double mode, the elastic-plastic deformation capacity and ultimate compressive strength of the concrete are improved; the steel plate supports can fully play a role as diagonal members, and provide high lateral-resistant rigidity and the high bearing capacity for a shear wall body; the flange portion of the shear wall body with the I-shaped section has a good restraint effect on a web wall, the bearing capacity, in the plane, of the combined shear wall and the bearing capacity, outside the plane, of the combined shear wall are remarkably improved, and thus the combined steel plate shear wall can have the high bearing capacity and the high elastic-plastic deformation capacity.

Description

technical field [0001] The invention relates to an I-shaped built-in round reinforcement cage and externally attached steel plate supporting steel plate shear wall and a method thereof, which are mainly used in the field of energy dissipation and shock absorption control in building structures. Background technique [0002] With the development of society and the improvement of economic level, there are more and more high-rise buildings. Reinforced concrete high-rise buildings with large quantities and wide areas are usually composed of beams, columns, floors, shear walls and cores. The shear wall and the tube body composed of the shear wall are the core parts of the high-rise building's seismic resistance, and the seismic performance of the shear wall and the core tube plays a vital role in the safety and reliability of the high-rise building. Especially in recent years, there are more and more large and complex high-rise buildings pursuing individualization, and the requi...

Problems solved by technology

There are two types of double-steel plate shear walls: outer-wrapped steel plates and built-in steel plates. The outer-wrapped double-steel plates can also be used as formwork, which is convenient for construction. In the past, there were few studies on double-steel combined shear walls, and they were limited to straight cross-sections. There is no research on composite shear walls with I-shaped cross-section double steel plates
