Highlights:

• The collapse behaviours of box type hull girder under cyclic ultimate moments were analysed by experiments and FEM.

• Coupled effect of structural complexity and loading condition on the collapse behaviour of the girders was investigated.

• The difference between single- and double-hull girders regarding the collapse behaviours was compared and deeply analysed.

• Suggestions on how to improve the structural safety under extreme load condition were provided.
