In practice of ship societies, current method of determining residual strength of ship hull structures after grounding is to totally remove the plastically damaged parts. As plastically deformed part of ship hull structures might still contribute considerable amount of strength, the method of total removal might be overly conservative. The article is oriented to quantify the residual strength of ship hull structures after grounding according to varied levels of plastic deformation. Literature study indicates that most of studies are focused on longitudinal residual strength of damaged ship structures, and transverse residual strength is rarely researched. Hence, it is target to study transverse residual strength after grounding damage, with implementation of a joint study of test and finite element simulation. The experiment gives validation to finite element models, and then an empirical formula can be derived by a series of FE simulations with the verified finite element model.
