Abstract

The invention relates to a self-resetting steel frame eccentric supporting system with large headroom and a flange plate, and belongs to the field of structural engineering. The self-resetting steel frame eccentric supporting system comprises two welded combined square steel tube columns, two square steel tube middle columns with cantilever beam sections, two I-shaped beam sections with inclined supporting rods, two Y-shaped inclined supports, an energy dissipation beam section, a combined self-resetting device and a plurality of connecting devices. By additionally arranging the combined self-resetting device consisting of a cable, a tool and a beam-column joint connecting device, the overall bearing capacity of a joint can be effectively improved, and the overstress load of the I-shaped beam sections caused by excessive cable pretension in the combined self-resetting device can be avoided; and the introduction of the design concept of energy-consuming beam section and eccentric support can play the role of "fuse" of the structure, the size and form of support can be changed meanwhile, door openings can be formed in the positions where the supports are set up, the steel consumptionis saved, and the economic benefits and applicability are improved.

Description

technical field [0001] The invention relates to a self-resetting steel frame eccentric support system with a large clearance and a flange, and belongs to the technical field of structural engineering. Background technique [0002] The prefabricated steel structure building system has become a new direction and new trend in the development of building steel structures. It has the advantages of standardization of design, factory production, assembly of construction, energy saving and environmental protection of green buildings, etc. Once the existing multi-high-rise public buildings and residential buildings are damaged by an earthquake, the buildings will cease to be used, which will have a serious impact on social economic recovery and the lives of the people. The post-earthquake repair work is time-consuming and labor-intensive. How to ensure the collapse resistance of the structure through reasonable frame design, and reduce the economic cost and time cost of post-earthqua...
