An eccentric support system with recoverable function steel frame with large headroom and flange

Abstract

The invention relates to an eccentric support system of a recoverable functional steel frame with a large clearance and a flange, belonging to the field of structural engineering. The system includes two welded composite square steel pipe columns, two square steel pipe center columns with cantilever beam sections, two I-beam sections with oblique support rods, two Y-shaped diagonal braces, one energy dissipation beam section and several Connecting device; each component of the system of the present invention is processed by the factory, and the accuracy and quality are easier to control. The site is all connected and installed by high-strength bolts, which is easy to realize rapid assembly; through special treatment at the joints of beams and columns, the cover plate can be made Buckling energy consumption can limit the excessive deformation of the cover plate, which can achieve the purpose of more stable node bearing capacity and more energy consumption; the introduction of energy-dissipating beam sections and eccentric support design concepts can play the role of structural "fuse" and change the The size and form of the support can open a door opening at the position where the support is set, which saves the amount of steel used and improves economic benefits and applicability.

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...
