Abstract

The invention relates to a self-resetting steel frame eccentric support system with large clearance, belonging to the field of structural engineering. The system includes two welded combined special-shaped columns, two I-beam sections with slanted support rods, two Y-shaped slanted braces, an energy-dissipating beam section, a combined self-resetting device and several connecting devices; The combined self-resetting device composed of , tooling and beam-column joint connection device can effectively improve the overall bearing capacity of the joint and can avoid the overstress load of the I-beam section caused by the excessive pretension of the cable in the combined self-resetting device; the introduction of energy consumption The design concept of beam section and eccentric support can play the role of structural "fuse". At the same time, the size and form of the support can be changed, and a door opening can be opened at the position where the support is set, saving steel consumption and improving economic efficiency and applicability.

Description

technical field [0001] The invention relates to a self-resetting steel frame eccentric support system with large clearance, 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-earthquake repair and r...
