[0002] The load-bearing system composed of reinforced concrete walls is called shear wall structure, which refers to a series of reinforced concrete walls set in the house structure for the main purpose of bearing horizontal loads (and also bearing vertical loads within the corresponding range). The higher the floor, the greater the impact of wind loads on it. In high-rise and super-high-rise house structures, horizontal loads will play a major role, and the house needs a large lateral resistance. The current mixed structure wall has low wall material strength and heavy weight, and the lateral resistance of the frame structure is weak, so it is only used in multi-story houses. Therefore, a new structure is needed in high-rise and super-high-rise house structures. System, which is the shear wall structural system; shear walls can be divided into reinforced concrete shear walls, steel plate shear walls, steel concrete shear walls and reinforced block shear walls according to structural materials. Among them, reinforced concrete shear walls are the most commonly used, with good integrity and high strength; at present, reinforced concrete walls are mainly used in daily life, which have high construction strength and require a large amount of wood as formwork during construction.
