Large-headroom flanged restorable-function steel-framed eccentrically braced system

Abstract

The invention relates to a large-headroom flanged restorable-function steel-framed eccentrically braced system and belongs to the field of structural engineering. The system herein comprises two welded combination square-steel pipe piles, two square-steel intra-pipe piles with a cantilever beam segment, two I-beam segments with a diagonal bracing rod, two Y-shaped diagonal brace, one energy-dissipating beam segment and a plurality of connection devices. All components of the system herein are processed in a factory, so that the precision and quality are easier to control. Connection and mounting are performed in situ completely through high-strength bolts, so that quick assembly is easy. Beam-column joints are specially treated, so that 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 energy-dissipating beam segments and eccentric bracing is introduced, so that structural 'fuse' effect can be achieved. By changing the size and form of bracing, a door opening can be set in the position wherein the bracing is arranged; therefore, steel consumption is lowered, and economic 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 and a flange, and belongs to the technical field of structural engineering. Background technique [0002] Since the reform and opening up, my country has achieved world-renowned achievements in the field of urban construction. At the same time, the traditional extensive construction mode with high energy consumption, high pollution, and low efficiency is still relatively common, which is incompatible with the development requirements of new urbanization, industrialization, and informatization. far cry. Changing the production mode of the existing construction industry and developing green buildings is an important strategy to lead the new normal of economic development and achieve sustainable development. The prefabricated steel structure building has the characteristics of standardized design, factory production, assembly construction, i...
