Abstract

The invention discloses a post-earthquake repairable assembly type latticed column with shear type energy dissipation dampers, and belongs to the technical field of structural engineering. The latticed column comprises a steel column, the shear type energy dissipation dampers, a first unilateral bolt group and a second high-strength bolt group. All the steel components are manufactured in a factory, the welding quality is easy to control, all the steel components only need to be hoisted and connected in a bolt assembly mode on a construction site, and the industrialization level and construction efficiency are high. The latticed column has the advantages of mechanical property and practical property at the same time, specifically, in the aspect of the mechanical property, the shear type energy dissipation damper structure is adopted to increase the height of the anti-side section of the latticed column, so that the lateral capacity and the energy dissipation capacity of the latticed column are improved; and in the aspect of practical performance, corrugated tie plates are used for being connected with the shearing energy dissipation plates, the steel consumption of the damper is reduced, good economical efficiency is achieved, and the function of an original structure can be recovered only by replacing the damaged damper after an earthquake.

Description

technical field

[0001] A post-earthquake repairable assembled lattice column with a shear type energy dissipation damper belongs to the technical field of structural engineering. Background technique

[0002] The development of steel structure buildings is closely related to the development of steel structure housing industrialization. To realize the industrialization of steel structure housing requires the standardization of parts and components. At present, high-rise buildings are the main direction of my country's construction industry. Therefore, a method suitable for high-rise buildings is proposed. The new high-efficiency assembled standardized steel structure system and the assembled standardized components based on the new steel structure system are the basis for realizing the industrialization of steel structure housing and promoting the development of steel structure buildings.

[0003] Steel structure buildings have become one of the key promotion projects in my co...
