Shear wall Introduction:
shear wall (shear wall) is also known as wind wall, seismic wall or structural wall. Walls in buildings or structures that bear mainly horizontal and vertical loads (gravity) caused by wind loads or earthquake action, to prevent structural shear (shear) damage. Also known as seismic wall, generally made of reinforced concrete.
It is divided into plane shear wall and barrel shear wall. Plane shear wall is used in reinforced concrete frame structure, lift plate structure and beamless floor system. In order to increase the stiffness, strength and collapse resistance of the structure, cast-in-place or precast reinforced concrete shear walls can be used in some parts. The cast-in-place shear wall and the surrounding beams and columns are poured at the same time, and the integrity is good. Tubular shear walls are used in high-rise buildings, high-rise structures and suspended structures, and are surrounded by the separation walls of elevator rooms, stairwells, equipment and auxiliary rooms. The tubular walls are cast-in-place reinforced concrete walls, and their stiffness and strength can withstand greater horizontal loads than that of plane shear walls.
The wall can be divided into load-bearing wall and shear wall according to the force characteristics, the former mainly bear vertical load, such as masonry wall; The latter is mainly subjected to horizontal loads. In the seismic fortification area, the horizontal load is mainly generated by the horizontal seismic action, so the shear wall is sometimes called the seismic wall.
Shear walls can be divided into steel plate shear walls, reinforced concrete shear walls and reinforced block shear walls according to structural materials. The reinforced concrete shear wall is the most commonly used.
