Abstract

The invention relates to a large-headroom restorable-function steel-framed eccentrically-braced system and belongs to the field of structural engineering. The large-headroom restorable-function steel-framed eccentrically-braced system comprises two welded combination special-shaped columns, two I-beam segments having an oblique support bar, two Y-shaped diagonal braces, one energy-dissipating beamsegment and a plurality of connection devices. All the components of the system herein are processed in a factory; the precision and quality are easier to control; connecting and mounting are formedin situ completely through high-strength bolts, so that quick assembly is easy to implement; beam-column joints are specially treated, a cover plate can buckle to dissipate energy, excessive deformation of the cover plate can also be limited, joint bearing capacity is more stable, and more energy can be dissipated; the design idea of the energy-dissipating beam segment and eccentric bracing is introduced, so that structural 'fuse' effect is achieved; brace size and shape are changed, a door opening can be set in the position where bracing is provided, so that steel consumption is lowered, andeconomic benefit and applicability are improved.

Description

technical field [0001] The invention relates to an eccentric support system of a recoverable functional steel frame with a 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 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 the earthquake, the buildings will be terminated, which will have a serious impact on social economic recovery and the lives of the people. The post-failure study shows that the main failure form of the structure is the failure of the beam-column joints. How to improve the energy dissipation capacity of the beam-column joints through reasonable design and rea...
