Abstract A procedure is developed, presented and evaluated to consider geometrical shape and structural imperfections in tapered web plate girders to calculate the ultimate bending strength under uniform stresses. The adjusted residual stress distribution in tapered web plates is used to determine ultimate loads, considering structural imperfections, using FEM / ANSYS 13, in addition to their corresponding elastic critical Eigen-Values, with and without residual stresses. Several figures represent the accurate as well as the approximate solutions, given by an equation or by ultimate pure and interaction stresses respectively |
