Development of efficient and precise methods for wind response predictions used in design calculations for long span bridges
Bridge technology is moving towards increasingly longer and more slender bridge spans, making the structures more susceptible to wind induced dynamic excitation. Due to this development, the design calculation methods needs to be evaluated and enhanced to ensure an economical and reliable design. NTNU have since the opening of the bridge in 2013 monitored the dynamic behavior of the Hardanger Bridge, one of the world’s most slender suspension bridges. The Hardanger Bridge is crossing the Hardanger fjord in complex terrain surrounded by steep mountains. In such terrain, the usual assumption that the wind field is stationary and homogenous is no longer a good estimation, demanding a more thorough description of the wind field parameters.
This project will aim to develop methods suitable to predict the long-term extreme response due to wind excitation including the statistical description of the wind field parameters in a complex terrain.
Objectives
- Evaluate the wind field models widely used today
- Establishing the statistical wind field parameters and comparing the full-scale measurements to possible methods used to predict these parameters along a future bridge deck
- Use the statistical wind field parameters to predict the long-term extreme response due to wind excitation
