11 th International Conference on Fast Sea Transportation 20 Conclusions Extended progressive collapse method: – Capable of predicting interframe and compartment level collapse modes for lightweight ship structures Validated with simple box girder and catamaran Further work has been identified including: – Investigate the suitability of the present method to predict biaxial bending moment response with overall collapse modes – Investigate the effects of different unsupported deck widths and lengths – Investigate the effects of transverse loads, such as may be caused by prying moment in a catamaran – Apply the methods to realistic ship structures 20
