The influence of residual stress distributions should be properly taken into account in the structural analysis of stiffened plates. The generally assumed residual stress distributions in the analyses often have constant values across their cross sections. This approximation is also applied to identical stiffeners that are constructed by different methods, such as rolled and built-up tee-bar stiffened plates. This paper focuses on buckling/plastic collapse behavior of rolled and built-up tee-bar stiffened plates with experimentally determined residual stress distributions in their cross sections. The structural behavior until collapse of these two types of tee-bar stiffeners is analyzed in detail, using residual stresses measured from experimental results. Various numerical modelling aspects of stiffened plated structures are briefly discussed and finally the influence of differences in residual stress distributions on buckling/plastic collapse behavior of continuous stiffened plates is studied based on selected results, using the Finite Element Method.
