Since the disastrous accidents involving large ore carriers occurred in rough seas and large box bridges in erection, the more reliable design methods of framed and plated structures, for example the design based on the collapse of structures with initial deflection, have been eagerly sought after. In this paper, a theory on the incremental finite element method is developed first and successively, contents of a computer program to analyze the collapse strength of framed and plated structures with initial deflection are described. Finally, the comparison of calculations with experiments on two types of structural components is shown for checking the applicability of the computer program.
