Abstract: A simple theory is developed for the coupled warping and cross‐sectional distortion at joints between thin‐walled I‐beams. Continuity of the joined flanges and the local character of the cross‐sectional distortion permit ...

Abstract: A finite‐element formulation is developed for limit analysis of perfectly plastic plates using triangular equilibrium elements and linear programming. The equilibrium elements are formulated in terms of three moment ...
