Abstract: (5669 Views)
Wave endurance time (WET) is a time domain method for evaluating the response of offshore structures under different storm conditions. In this method, intensifying artificial records named wave functions (WFs) are generated in place of various random records of extreme sea states. In this regard, the computational costs are reduced, and reliability of structures is evaluated by the endurance time. In this study, a description of WET concept is presented, and also generation of initial type of WFs is thoroughly addressed for the Persian Gulf region. To consider the accuracy of this method, the results of WET method are compared with typical 3h extreme wave simulations for maximum base shear and deck displacement. The results indicate that there is acceptable agreement between two approaches.
