Abstract

The invention relates to the technical field of steel structures in building industry and discloses a prestressed assembled middle column steel frame recoverable in function. The prestressed assembled middle column steel frame comprises a frame beam, two frame columns, an upper middle column, a friction energy-consuming device and a lower middle column, the frame beam is arranged horizontally, the frame columns are vertically arranged at two ends of the frame beam, the frame columns are movably connected with the frame beam, the upper middle column is vertically arranged below the frame beam, the top of the upper middle column is fixedly connected with the frame beam, and the upper middle column, the friction energy-consuming device and the lower middle column are sequentially connected from top to bottom. Rigidity of the whole steel frame can be enhanced; energy dissipation of the steel frame can be improved through the friction energy-consuming device, so that overall deformation degree of the prestressed assembled middle column steel frame is lowered greatly, in other words, inter-layer displacement angle response is reduced, stability of a whole building is improved, designing requirements are met, and safety in operation can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of steel structures in the construction industry, in particular to a prestressed assembled intermediate column steel frame with recoverable functions. Background technique [0002] In the construction industry, the existing prestressed steel frame with recoverable function generally includes horizontal beams, two vertical columns fixed at both ends of the beams, frictional energy-dissipating bolts and prestressed steel strands. When it is in a high-seismic area or an area with a large structural span, under the action of external force, due to its structural and rigidity problems, it is easy to cause a large deformation of the entire steel structure, that is, the response of the interstory displacement angle is too large, so that the entire building is reliable. The performance is poor, it is difficult to meet the design requirements, and it is easy to cause safety accidents. Contents of the invention [...
