C-shaped steel-friction damper combined energy dissipation structure and method

Abstract

The invention relates to a C-shaped steel-friction damper combined energy dissipation structure. The C-shaped steel-friction damper combined energy dissipation structure comprises a connecting base, a large C-shaped steel energy dissipation device and a friction device. The connecting base comprises a left connecting base body and a right connecting base body which are symmetrically arranged, and the large C-shaped steel energy dissipation device and the friction device are installed between the left connecting base body and the right connecting base body. The C-shaped steel-friction damper combined energy dissipation structure is arranged at the connecting position of a pier column and a straining beam, when the structure is subjected to an earthquake load, the large C-shaped steel energy dissipation device can absorb transverse load energy dissipation through deformation, and the friction device absorbs longitudinal load energy dissipation through relative friction of the friction device. The double-column pier with the straining beam is mainly used in the field of bridges, the straining beam can be assembled, replaced and repaired, the whole life cycle cost is reduced, the brittle failure mode of shear failure of the straining beam is changed into ductile failure, the anti-seismic performance of the double-column pier is enhanced, and sufficient energy consumption under the earthquake action is achieved.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a C-shaped steel-friction damper combined energy dissipation structure and method. Background technique [0002] With the rapid growth of my country's economic strength, the demand for transportation infrastructure is increasing, and the technical requirements for basic buildings such as roads and bridges are getting higher and higher. However, my country has a vast territory and complex terrain, especially in the southwestern region surrounded by high mountains, with great differences in terrain height. It is extremely difficult to adopt the traditional on-site construction method, the construction period is long, and the pouring of concrete on site pollutes the environment. At the same time, the quality of concrete cannot be strictly guaranteed. Prefabricated assembly technology, due to the characteristics of factory prefabrication and on-site assembly, ensures the quality of ...
