This paper describes the development of an analysis model, which is suitable for the evaluation of the hull girder response of ships due to waves including torsion effect. To this aim, springing effects on hull girder was re-evaluated including non-linear wave excitations and torsional vibrations of the hull. The Timoshenko beam model was used to calculate the stress distribution on the hull girder and solved using superposition method. The strip method was employed to calculate the hydrodynamic forces and moments on the hull. Viscous effects, which may be important for calculation of wave-induced twisting moment on the hull, were accounted for in a simplified manner. Example calculation results show a reasonable agreement with previous results for both symmetric and anti-symmetric responses.
