Shear walls are also called wind-resistant walls or seismic walls and structural walls. Walls in houses or structures that are mainly subjected to horizontal loads and vertical loads {gravity} caused by wind loads or earthquakes. Prevent structural shear damage.
Split plane shear wall and cylindrical shear wall. Plane shear walls are used in reinforced concrete frame structures, lifting slab structures, and beamless floor systems. In order to increase the rigidity, strength and collapse resistance of the structure, reinforced concrete shear walls can be cast-in-place or prefabricated in certain parts. The cast-in-place shear wall is poured simultaneously with the surrounding beams and columns, and the integrity is good. The tube shear wall is used in high-rise buildings, high-rise structures and suspended structures. It is surrounded by partition walls of elevator rooms, stairwells, equipment and auxiliary rooms. The tube walls are all cast-in-place reinforced concrete walls with rigidity and The strength is higher than that of the plane shear wall, which can withstand larger horizontal loads.
Walls can be divided into load-bearing walls and shear walls according to the characteristics of their forces. The former mainly bears vertical loads, such as masonry walls; the latter mainly bears horizontal loads. In the seismic fortified area, horizontal loads are mainly generated by horizontal earthquake action, so shear walls are sometimes called seismic walls.
According to structural materials, shear walls can be divided into steel plate shear walls, reinforced concrete shear walls and reinforced block shear walls. Among them, the reinforced concrete shear wall is the most commonly used.
