A new model for collapse analysis of stiffened plate structures is formulated within the Idealized Structural Unit Method (ISUM). By idealizing material and geometrical nonlinearities, larger structural units are defined as an element in ISUM than in conventional Finite Element Analysis (FEA). The stiffened plate model consists of ISUM plate elements and beam-column elements. Comparisons with FEA show its accuracy in predicting the collapse behaviour of typical stiffened plates. Its applicability to system analyses is demonstrated by investigating box girder specimens.
