Quake-resisting method of building structure

Abstract

The invention discloses a quake-resisting method of a building structure. The method involves an existing building frame, and includes the steps that first, first steel ropes are led out from beam-column joints of upper beams at joint space of the building frame, meanwhile, second steel ropes are led out from beam-column joints of lower beams, the other ends of the second steel ropes are anchoredinto beam-column joints on the other sides of the upper beams, then the first steel ropes and the second steel ropes are connected through connectors, and then every two connected steel ropes are tensioned or subjected to prestress to form a quake-resisting device; the quake-resisting devices are arranged in pairs in each frame and at all floors. Beams and columns in a whole building are connectedin a tied mode through the quake-resisting devices with steel rope assemblies, and therefore the quake-resisting devices can provide extra tension for the building structure to prevent the building structure from being greatly deformed in an earthquake, and the quake-resisting capacity of the building structure is improved.

Description

Technical field [0001] The invention relates to an anti-seismic method of a building structure, belonging to the technical field of anti-seismic of a building structure. Background technique [0002] At present, the seismic resistance of the existing building frame, frame-shear or frame-tube structure usually adopts shear walls and energy dissipation devices (dampers). The shear wall has large lateral rigidity, bending deformation under the action of horizontal force, and the difference of cooperative work with the shear deformation of the frame structure, and the material consumption is high, and the vertical load is insufficient; the dampers are expensive , Occupies a large space and low work efficiency. Oblique support columns are also used in traditional earthquake-resistant building structures, but the existing diagonal support columns are troublesome in construction, have poor seismic effects, and have limited practicability. Summary of the invention [0003] In order to o...

AI Technical Summary

Problems solved by technology

The shear wall has a large lateral stiffness, and is bent under the action of a horizontal force. There is a difference in cooperation with the shear deformation of the frame structure, and the material consumption is large, and the force of the vertical load is insufficient; the cost of the damper is high , takes up a lot of space and low work efficiency

Diagonal support columns are also used in traditional earthquake-resistant building structures, but the construction of existing oblique support columns is cumbersome, the anti-seismic effect is poor, and the practicability is limited.
