Embodiment Construction

[0034] The present invention is described in detail below in conjunction with accompanying drawing:

[0035] as attachedfigure 1 As shown, in the post-earthquake self-resetting multi-section beam shear wall steel frame that can be assembled in the present invention, the special-shaped columns involved are respectively: the frame corner frame column 1 is the L-shaped column, and the frame side frame column 2 is the T-shaped column , the frame column 3 in the middle of the frame is the cross-shaped column;

[0036] as attached figure 2 As shown, in the post-earthquake self-resetting multi-section beam shear wall steel frame that can be assembled in the present invention, it mainly includes L-shaped, T-shaped, and cross-shaped joint forms, and the cross-shaped joint is taken as an example in the figure. The cross-shaped node connection is the connection between the frame column 3 in the middle of the frame and the I-beam 4 at the end. Specific connection steps: the hoisting eq...

Abstract

The invention discloses a post-earthquake self-resetting assembled multi-section beam shear wall steel frame, which is characterized in that a I-shaped steel beam is connected with different forms ofspecial-shaped columns through web angle steel and flange angle steel to form a weldless full-bolt connection mode; a middle I-shaped beam is connected with end I-shaped beams through web connecting plates and high-strength silicone rubber plates to form a weldless full-bolt connection mode with good ductility and strong energy dissipation ability; prestressed steel cables are applied to the junction of the weldless full-bolt middle I-shaped beam and the end I-shaped beams to form prestressed post-earthquake self-resetting nodes, and prefabricated concrete-profiled steel plate composite floorslabs or poured concrete floor slabs are assembled after the nodes are sequentially connected to form a post-earthquake self-resetting assembled multi-section beam shear wall steel frame structure system.

Description

technical field [0001] The invention relates to a post-earthquake self-resettable multi-segment beam shear wall steel frame, which belongs to the technical field of earthquake prevention and disaster reduction. Background technique [0002] Japan's steel structure houses account for more than 60% of all houses. Multiple earthquakes have proved that steel structure buildings have greatly improved seismic performance compared with reinforced concrete buildings, and the difficulty of post-earthquake repairs has been greatly reduced. Therefore, vigorously developing steel structure buildings is the only way to improve the quality of residents' housing, especially steel structures with high technological content should be valued and developed. [0003] Steel structure prestressing technology has developed rapidly, the most representative of which is the Beijing University of Technology Gymnasium. Innovative research on structural system innovation. However, in the frame structu...
