Civil air defense wall refers to an underground protective building built separately for the protection of personnel and materials in wartime, civil air defense command and medical rescue, and a basement built in combination with ground buildings that can be used for air defense in wartime. Shear wall is mainly a wall that bears horizontal load and vertical load (gravity) caused by wind load or earthquake in buildings or structures to prevent structural shear (shear) damage.
Extended data
Shear walls can be divided into plane shear walls and tube shear walls according to their structures:
1, plane shear wall
If buyers want to rebuild their houses, they must first find out what shear walls are. Plane shear wall is a common shear wall, which is often used in reinforced concrete frame structure, raised slab structure and flat floor system. In order to increase the rigidity, strength and collapse resistance of the structure, reinforced concrete shear walls can be cast-in-place or partially prefabricated. Cast-in-place shear wall and surrounding beams and columns are poured at the same time, which has good integrity.
2, the tube shear wall
In addition to plane shear walls, there are also tube shear walls. The tube shear wall is used for high-rise buildings, towering structures and suspension structures, and is surrounded by partition walls of elevator machine rooms, stairwells, equipment and auxiliary rooms. The tube walls are all cast-in-place reinforced concrete walls, and their stiffness and strength are higher than those of plane shear walls, which can bear larger horizontal loads.
