Document Type: Proceeding Paper
Part of: Structural Safety and Reliability
Abstract: This paper presents a cumulative fatigue damage formulation in stochastic variable space using bilinear SN model and the Palmgren-Miner's rule for evaluating the fatigue reliability of offshore structures. Statistical stress characteristics are determined from a spectral analysis procedure based on a modified modal analysis technique which ensures an exact result in the quasi-static part of the response. Uncertainties arising from different origins are characterized by representative stochastic variables in the analysis. The reliability index is calculated employing the Level II Approximate-Full Distribution method. An example is also presented to demonstrate the calculation results and sensitivities of design variables.
