| 摘 要： | Residual strength assessment and prediction has been introduced in the project studies, including the determination of risk failure scenario, the change law of structural capacity and load effects in the damage of ship structure, the models for structural response and ultimate strength analysis, and dynamical model of reliability assessment. In addition, the project has improved the calculation method of ship ultimate load -bearing capacity, and studied the change law, assessment criteria of residual strength, and the method of predicting lifetime for aging ships. The valuable conclusions have been obtained by a large number of engineering calculations. The project and its extended results can provide theoretical foundation and background condition to make risk rule and modem design system, and can implement risk analysis and formal safety assessment for the marine world. The results will improve design quality and shipping safety of ship and offshore and enhanced their society and economic benefits.
