Abstract

The invention discloses a multidirectional vibration double-control device suitable for a steel box girder bridge, which comprises four tension and compression viscous dampers, two square hard steel pipes, two pieces of strip-shaped corrugated energy dissipation soft steel, two steel cables and two pieces of fan-shaped corrugated energy dissipation soft steel, each tension and compression viscous damper comprises an outer cylinder, a guide rod, a sealing element, viscous liquid and a limiting plate, according to the device, the vibration double-control performance of the bridge can be improved, and meanwhile the overall stability is improved.

Description

technical field [0001] The invention belongs to the technical field of bridges, and relates to a multi-directional vibration and vibration dual-control device suitable for steel box girder bridges. Background technique [0002] Wind disasters, earthquakes, etc. are common natural disasters. In recent years, the global climate has changed greatly, typhoons and hurricanes have become more rampant, and wind damage losses have also increased every year. Earthquakes also occur continuously, causing very heavy loss of life and property, among which the damage and collapse of civil engineering structures is one of the main parts of the loss. my country is currently in the stage of vigorous development of traffic engineering construction. A large number of extra-large-span bridge structure systems continue to emerge. The bridge structure is more sensitive to the effects of wind and vehicles, and its vibration amplitude continues to increase. The vibration-vibration dual-control des...
