Abstract

The present invention discloses a shear wall combining a concrete filled steel tube side frame with seams or an opening. The shear wall comprises a reinforced concrete wall body (2) internally provided with reinforcing meshes (8), and concrete filled steel tubular columns (1) arranged at two sides of the reinforced concrete wall body, connecting members (6) are arranged between the concrete filled steel tubular columns and the reinforced concrete wall body, one end of each connecting member is fixed onto the concrete filled steel tubular column (1) while the other end is anchored into the reinforced concrete wall body (2), seams (9) and an / or an opening (10) are disposed in the reinforced concrete wall body (2), and an energy dissipation device (11) is arranged inside the opening (10) as required. Under the condition of ensuring lateral stiffness of the structure is satisfactory, through arrangement of the seams and the opening, ductility of the combined shear wall is raised, and deformability of the shear wall is also raised; through arrangement of the energy dissipation device, the energy-dissipating capacity of the shear wall is raised, and thus the anti-seismic property of the structure under actions of major earthquakes is improved; and through different parameter designs, requirements for performance-based structural designs are met.

Description

technical field [0001] The invention belongs to the technical field of concrete building components, and in particular relates to a steel pipe concrete frame combined slotted or holed shear wall. Background technique [0002] Shear wall is also called aseismic wall or wind-resistant wall, structural wall. Shear wall is a structural component in a house or structure that mainly bears horizontal effects such as earthquake action or wind load. It can prevent excessive deformation of the structure and avoid shear damage, so it is widely used in building structures. Existing shear walls are generally made of reinforced concrete. Because of their high lateral stiffness, they are used to bear internal forces caused by various horizontal loads and can effectively control the horizontal displacement of the structure. [0003] Ordinary reinforced concrete shear walls have poor deformation capacity and energy dissipation capacity. When they are used in high-rise and super high-rise bu...
