Abstract

The invention discloses a friction damper with a gap with additional rigidity, which comprises an outer cover steel plate, a friction plate, an I-shaped plate, a rectangular steel sheet, a one-shaped plate, a U-shaped plate, and high-strength friction bolts. Among them, the outer cover steel plate, the I-shaped plate, the rectangular steel sheet, the one-shaped plate, and the U-shaped plate are stacked sequentially from top to bottom and symmetrically distributed around the one-shaped plate and the U-shaped plate. The outer cover steel plate, the outer rectangular steel sheet and the U-shaped plate are fixed by the outer friction high-strength bolts; the friction plate, the inner rectangular steel sheet, and the one-shaped plate are fixed by the inner friction high-strength bolts. The I-shaped board is placed on the upper and lower sides of the one-shaped board and the U-shaped board. Compared with the traditional friction damper, the I-shaped plate is subjected to tension during loading, which provides another defense line for energy consumption and can increase the rigidity of the main structure and improve the anti-seismic performance of the main structure.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a friction damper with additional rigidity for reducing the seismic response of engineering structures. Background technique [0002] Due to the strong suddenness, heavy casualties, and huge economic losses, the earthquake has a wider and stronger social impact than other natural disasters, and often produces a series of chain reactions, which have a negative impact on the social activities and economic development of a region or even a country. The event had a huge impact. In the anti-seismic field of construction engineering, shock absorption technology can effectively reduce earthquake disasters. At present, friction dampers are the most important shock absorption devices. Friction dampers are a type of dampers that use the friction force generated by the relative action of friction surfaces in a pressurized environment to convert the external input energy into heat energy so a...
