A two-way rocking cylinder anti-seismic structure

Abstract

The invention relates to a two-way swinging cylinder earthquake-resistance structure, belonging to the technical field of structural engineering earthquake resistance. The two-way swinging cylinder earthquake-resistance structure comprises a reinforced concrete cylinder wall, an oblique prestretched cable, an energy consumer, high-strength prestressed tendons, anchoring accessories and a foundation. Because the oblique prestretched cable is arranged in a concrete rectangular cylinder and connected with the energy consumer, the lateral rigidity of the structure is ensured, and the energy consuming capacity and the self-resetting capacity of the structure are enhanced. Because the vertical high-strength prestressed tendons are arranged in the concrete rectangular cylinder to strengthen the connecting performance of the structure and the foundation and further improve the rigidity of the structure, the two-way swinging cylinder earthquake-resistance structure is suitable for the medium and high-rise industrial and civil buildings with the earthquake-resistance fortification intensity of more than 6 degrees. The two-way swinging cylinder earthquake-resistance structure is simple and convenient to construct, has good energy consuming capacity and can resist multi-dimensional earthquake. In addition, the two-way swinging cylinder earthquake-resistance structure has good self-resetting characteristic and small residual deformation and is easy to repair after being slightly damaged.

Description

technical field [0001] The invention relates to an anti-seismic structure of a two-way swaying cylinder, which belongs to the technical field of anti-seismic and shock absorption of structural engineering. Background technique [0002] At present, building structures generally ensure the safety of the structure by controlling the deformation of the structure under earthquake loads. However, large non-recoverable nonlinear plastic deformations will also occur under rare earthquakes. Some post-earthquake building structures and bridge structures show that if the structures do not collapse but have large plastic residual deformations, it is extremely difficult to restore these structures to their original positions, and the repair cost will even exceed that of new structures. On the other hand, if the seismic performance of the structure is to be improved, the structure must have better energy dissipation capacity, which means that the structure needs to be damaged greatly, and...

Problems solved by technology

[0002] At present, building structures generally ensure the safety of the structure by controlling the deformation of the structure under the action of earthquake loads, but at the same time, large non-recoverable nonlinear plastic deformations will also occur under rare earthquakes

Some post-earthquake building structures and bridge structures show that if the structure does not collapse, but has a large plastic residual deformation, it is extremely difficult to restore these structures to their original positions, and the repair cost will even exceed that of new structures

On the other hand, if the seismic performance of the structure is to be improved, the structure must have better energy dissipation capacity, which means that the structure needs to be greatly damaged, and the final residual deformation of the structure must be large

In order to reduce or even eliminate the damage and residual displacement of the structure while ensuring the energy dissipation capacity of the structure, researchers have conducted research on swing structures. For example, some researchers have studied and analyzed swing walls and swing columns, and the results show that such structures Small damage, small residual deformation, but reduced energy dissipation capacity
