The contents of this paper are summarized as follows. (1) The computer program based on incremental finite element method which had the layered triangular plate element and layered stiffener element as main elements was made to analyze non-linear behaviours of plate structures including buckling collapse of plate structures with initial deflections. (2) The experiments of three girder models with initially deflected end corners were conducted to search buckling collapse loads and modes. (3) The comparison of the computed results with the experiments mensioned above showed good agreements on both collapse loads and modes. As the computing time required is not so long, the numerical analysis is considered to be applicable to obtain the tendency of the influences of initial deflections on the collapse.
