Example, it is diversified that wind endanger to caused by bridge, and bridge floor wind-induced vibration can cause people to lose the sense of security, serious or even meeting
Suspend traffic.Accumulation over time, bridge structure may shift to an earlier date fatigue rupture, most serious be cause bridge ruin people die it is miserable
It is acute.Present wind engineering of bridge mainly studies different types of rridges under the conditions of different wind fields, and bridge structure static(al) effect is rung with power
Should.However, for cross a river Longspan Bridge over strait, influence of the wind to bridge is not active force and knot of the wind to structure merely
Structure in itself wind effect under dynamic response.Need to consider that stormy waves is to shadow caused by wind under bridge because its flexibility is larger, during design
Ring effect.Because in some cases, the influence can influence and change bridge Wind Field characteristic, especially natural wind field
All it is typical random process over time and space, some emergency cases occurs at any time.In addition, research shows, rainfall pair
The influence of bridge structure depends primarily on Wind field variety caused by space raindrop and the attachment of girder surface moisture film.For in marine site
For bridge or oil platform, it is subjected to the invasion and attack of wave, high wind, heavy rain, thus, consider these three kinetic factors
Coupling could effectively, truly reflect and solve engineering problem.
The content of the invention
In view of this, it is an object of the invention to provide a kind of achievable wind, wave, rain coupling experimental system,
Experiment basis are provided for further coupling of the research wind, wave, rain to bridge or oil platform in marine site.
