Anti-seismic building structure provided with steel frame and crossed central support with link beams

Abstract

The invention discloses an anti-seismic building structure provided with a steel frame and crossed central support with link beams. The anti-seismic building structure comprises rectangular concrete filled steel tubular columns, steel beams, the link beams and support rods. The strength grade of the rectangular concrete filled steel tubular columns, the steel beams, the link beams and the support rods is gradually decreased sequentially. The support rods, the link beams, the steel beams and the rectangular concrete filled steel tubular columns yield sequentially under side force. According to the anti-seismic building structure, an industrial production line can be adopted for production, fabricated construction is conducted in site, the requirements for green construction and index formation are met, the construction technological level and construction quality can be improved easily, development of steel structure buildings is promoted, the requirements for the overall anti-seismic property and the lateral displacement resistance of high earthquake intensity regions are met, and the anti-seismic building structure has the advantages of being sufficient in bearing capacity, rigidity and anti-seismic property, and the like.

Description

technical field [0001] The invention belongs to the technical field of construction engineering and relates to an anti-seismic building structure with a steel frame with energy-dissipating beams and a cross-shaped central support, which can be widely used in residential buildings with anti-seismic requirements such as houses and apartments. Background technique [0002] Steel structures have comprehensive advantages such as recyclable resources and less environmental pollution, highlighting the characteristics of green and environmental protection, in line with the basic idea of ​​reducing resource consumption and protecting the ecological environment proposed in the "13th Five-Year Plan". At present, the development of steel structure is facing good opportunities. Steel is a green building material, and steel structure has the characteristics of green ecological buildings. Its development will inevitably attract the attention and support of the government and all parties in ...

AI Technical Summary

Problems solved by technology

[0003] Traditional residential buildings mainly use concrete structures, which require a lot of labor during construction, and consume a lot of wood during on-site construction, generating a lot of waste water and dust

In recent years, my country's construction industry has continued to develop rapidly, but the relatively slow development of steel structure residences, the existing steel structure system is not perfect, the structure system is single, and does not match the characteristics of residential apartments, and the structural system in higher intensity areas cannot reflect steel structures. It has good anti-seismic performance and weak stiffness at the same time, which is not conducive to popularization and utilization in multi-high-rise buildings
