Abstract

In this paper, the authors describe the results of theoretical and experimental investigations into fundamental behaviors of plates and stiffened plates in compression considering the influences of initial imperfections due to welding. Elastic and elastic-plastic large deflection analyses were performed on nonlinear behaviors to evaluate the compressive ultimate strength of plates and stiffened plates. Buckling analysis was also performed to estimate the influences of welding residual stresses on elastic, elastic-plastic or plastic buckling strength of compressed plates and stiffened plates. The results of investigation indicate that initial deflection reduces the strength and regidity of compressed plates and stiffened plates. The welding residual stresses also reduce the compressive strength except when a stiffened plate buckles in an overall mode.
