Abstract

The invention discloses a self-reset girder-grid friction wall structural system and belongs to the technical field of structural engineering earthquake proofing. A grid metal structure (7) is fixed in a frame unit formed by a reset girder (1) and a swing pillar (2); two building body walls (3) are arranged at the outside of the grid metal structure (7); the self-reset girder (1) and the swing pillar (2) are fixedly connected by angel steel (16); a prestressed steel bar (17) is precast in the self-reset girder (1) by a post-tensioning method; two ends of the prestressed steel bar (7) are anchored at the outside of the swing pillar (2) by anchorages (5); the swing pillar (2) is placed on a foundation base (4); rubber gaskets with a certain thickness are paved at the contacting positions between pillar legs and the foundation base (4). Under the action of an earthquake, the swing pillar (2) and the self-reset girder (1) rotate, the grid metal structure (7) is driven to be deformed, and the swing pillar (2), the self-reset girder (1) and the grid metal structure (7) cooperatively work and consume energy in steps, so the aims of reducing horizontal displacement of the structure and enhancing the energy dissipation capacity of the structure are achieved.

Description

technical field

[0001] The invention relates to the field of anti-seismic technology of civil engineering, and relates to an anti-seismic system of a self-resetting beam-grid friction wall structure. Background technique

[0002] At present, foreign scholars have carried out a series of researches on self-resetting beams and frictional walls, and made some research progress.

[0003] In terms of self-resetting technology. The so-called "self-resetting" means that the structure that relaxes the constraints first undergoes a certain bending deformation under the action of an earthquake, and then sways after exceeding a certain limit, and the structure returns to its original position through prestressing. The self-resetting technology can effectively eliminate the residual deformation of the structure, so that the structure can continue to be used after simple repairs after the earthquake, saving production costs. The idea of โ€‹โ€‹"self-resetting" originated from the study of p...
