摘要：
A new simplified model for stiffened plates in collapse analyses is developed. The model consists of large plate elements and beam-column elements. It is formulated according to the typical collapse modes of stiffened plates under longitudinal thrust, which are investigated by conventional Finite Element Analysis (FEA). Comparisons with FEA show the excellent applicability of the model to typical stiffened plates in marine structures and its accuracy. To demonstrate the application of the model to offshore structures, the collapse behaviour of a transverse strip of a Very Large Floating Structure (VLFS) in longitudinal waves is examined.
