摘要: Abstract Due to both wave and wind fluctuations, the steel foundations of offshore turbines are highly submitted fatigue. To date, current methods fatigue design proposed in regulations not devoted structural optimization consideration time-variant hazards. We propose hence an incremental two-scale model damage order follow time evolution damage. This temporal allows updating parameters using records from Structural Health Monitoring. In this paper, we focus on Bayesian sensitivity analysis assessment material parameters.
