Frame shear wall structure with swinging energy dissipation column

Abstract

The invention discloses a frame shear wall structure with a swinging energy dissipation column. One end of a frame beam is fixed to a shear wall, the upper end of the frame column is fixedly connectedwith the other end of the frame beam, a reinforced concrete pier is of a groove-shaped structure, the lower end of the frame beam is inserted into the reinforced concrete pier, two energy dissipationcomponents are separately located in the reinforced concrete pier, and the two energy dissipation components are separately located on two sides of the frame column. Second screw rods penetrate through second end plates, first end plates of the side walls of the reinforced concrete pier and flanges of the frame column in sequence, the end portions of the steel plates are fixed to the flanges of the frame column, first limiting pieces are arranged at one ends of first screw rods, and second limiting pieces are arranged at the other ends of the first screw rods after penetrating through the bottom of the reinforced concrete pier and the steel plates. First springs and second springs are arranged on the first screw rods, and third springs are arranged on the second screw rods. The frame shear wall structure has a self-resetting effect and is convenient to replace after earthquake damage.

Description

technical field [0001] The invention belongs to the field of anti-seismic and shock-absorbing civil engineering, and relates to a frame shear wall structure with swinging energy-dissipating columns. Background technique [0002] The traditional anti-seismic concept generally enhances the anti-seismic capacity of the structure by increasing the stiffness, strength and ductility of the structure, but this approach usually leads to serious damage to the structure after the earthquake, making it difficult to repair. In recent years, rocking structural systems have become one of the important research directions in the field of earthquake engineering because they can significantly reduce the post-earthquake damage of structures. At present, there are various implementation methods such as swing column system, swing wall system, combination of swing structure and energy dissipation and shock absorption device. [0003] The rocking system is a self-resetting passive anti-seismic s...

Problems solved by technology

[0004] The swinging column system also has self-resetting ability. At present, the self-resetting ability of the swinging column system is mainly provided by prestressed unbonded steel strands. Not only is the construction difficult, but the self-resetting effect is not obvious

In addition, the current swing column system is not easy to replace after earthquake damage
