Reliability-based calibration of fatigue design guidelines for ship structures

摘要: A simple reliability-based framework is applied to calibrate a new set of fatigue design guidelines. This guideline considers two different approaches for the assessment both loads, stresses and local stress raising effects, partial safety factors must be given any combination these approaches. For calibration, lognormal reliability format adopted because hereby-derived can combined arbitrarily. means that with few basic factors, together calculation determined easily. In present paper format, modeling uncertainties selected target index are explained. Based on this, calibrated derived presented. Finally, through numerical example in order show applicability satisfactory results found.
