Shear wall (shear wall), also known as wind wall, seismic wall or structural wall. House or structure in the main wind load or seismic action caused by the horizontal load and vertical load (gravity) of the wall, to prevent structural shear (shear) damage.
It is divided into plane shear wall and cylinder shear wall. Plane shear walls are used in reinforced concrete frame structures, rising slab structures, and beamless floor cover systems. In order to increase the stiffness, strength and collapse resistance of the structure, in some parts of the cast-in-place or prefabricated assembly reinforced concrete shear wall. Cast-in-place shear walls are cast at the same time as the perimeter beams and columns for good integrity. Cylinder shear wall used in high-rise buildings, towering structures and suspended structures, by the elevator, stairwells, equipment and auxiliary rooms spacing wall enclosure, cylinder walls are cast-in-place reinforced concrete walls, its stiffness and strength than the plane shear wall can withstand greater horizontal loads.
Walls can be divided into load-bearing walls and shear walls according to the force characteristics, the former to withstand vertical loads, such as masonry walls; the latter to withstand horizontal loads. In the seismic defense zone, the horizontal load is mainly generated by the horizontal seismic action, so the shear wall is sometimes called seismic wall.
Shear wall[1] can be divided into steel plate shear wall, reinforced concrete shear wall and reinforced block shear wall according to the structural material. Among them, reinforced concrete shear walls are most commonly used.
