Basic concepts and approaches related to the ultimate shear strength are briefly reviewed and a FEM-based tool is presented and advocated as useful for further studies. To investigate the plastic/collapse behavior pf plate girder in shear, especially when their geometry is complicated due to the present of holes and stiffeners one can only use non-linear elastic-plastic large deflection FEA . the dedicated computer code presented herein is a useful tool for the structural analysis , as well as for the rational design specialist , since the pre-and post-processing tasks as well as the calibration on experimental results are generally acknowledged as too time consuming.
