Swinging type self-centering steel frame and concrete shear wall anti-seismic system

Abstract

The invention provides a swinging type self-centering steel frame and concrete shear wall anti-seismic system, which comprises a first steel column (41), a second steel column (42), a concrete wall (5) and friction parts. The first steel column (41) and the second steel column (42) are oppositely arranged in parallel, the concrete wall (5) is located between the first steel column (41) and the second steel column (42), the friction parts comprise a first friction part and a second friction part, and the structure of the first friction part is identical to that of the second friction part; and the first steel column (41) is connected with the concrete wall (5) via the first friction part, the second steel column (42) is connected with the concrete wall (5) via the second friction part, the concrete wall (5) is connected with a foundation beam (12) via a vertical prestress wire (7), a floor is fixedly connected with the concrete wall (5), and the first steel column (41) and the second steel column (42) are respectively hinged to the foundation beam (12) via hinging devices (8). Damage of a total steel frame structure can be reduced when in earthquake by the aid of the swinging type self-centering steel frame and concrete shear wall anti-seismic system, and an anti-seismic performance is improved.

Description

technical field [0001] The invention is an assembled anti-seismic structure system, which is used to improve the ability of the steel frame structure to resist lateral deformation, realize the automatic reset of the structure after the earthquake, and eliminate or reduce the residual deformation and damage of the steel frame structure under the earthquake. The friction device dissipates seismic energy, reducing the cost of post-earthquake repairs. Background technique [0002] Earthquake is one of the natural disasters faced by all mankind, which poses a serious threat to people's lives and property safety. Earthquake damage surveys at home and abroad have shown that for common steel frame structures, the column base and beam-column joint areas are easily damaged areas, and these parts are just the key parts of the structure to ensure the bearing capacity, and their damage will often lead to the collapse of the structure . At the same time, for the steel frame structure sy...
