Abstract

The invention relates to a self-resetting steel frame eccentric supporting system with large headroom, and belongs to the field of structural engineering. The self-resetting steel frame eccentric supporting system comprises two welded combined special-shaped columns, 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 consumption is 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 large clearance, belonging 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 structure, with the advantages of design standardization, production factoryization, construction assembly, green building energy saving and environmental protection. Existing multi-high-rise public buildings and residential buildings, once earthquake damage occurs, the buildings will be terminated, which will have a serious impact on social and economic recovery and people's lives, and the post-earthquake restoration work will be time-consuming and laborious. How to use a reasonable frame design to not only ensure the collapse resistance of the structure in an earthquake, but also reduce the economic and time costs of post-earthquake repair an...
