Embodiment Construction

[0034] The present invention will be described below with reference to the accompanying drawings.

[0035] The present invention provides a frame that arranges one span or several spans in a steel frame in a swinging geometrically variable form (the following discussion is all about this span frame)——the steel column foot of this span is connected to the Base hinge. A concrete wall is used to provide lateral rigidity for the span frame, and the concrete wall and the steel column are connected by a friction member. The joint of the friction member has the ability to displace the steel column and the concrete wall in the same horizontal direction and move relative to each other in the vertical direction. properties, and energy can be dissipated due to friction when a vertical relative displacement occurs. The bottom of the concrete wall here is separated from the foundation, and is tied to the foundation through several bundles of vertical prestressed tendons passing through th...

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...
