INFLUENCE OF IN-PLANE DISPLACEMENTS AT THE BOUNDARIES OF RIGID-PLASTIC BEAMS AND PLATES

An approximate theoretical rigid-plastic study has been undertaken into the influence of small in-plane displacements at the boundaries of various laterally loaded beams. The most interesting feature of these theoretical predictions is the remarkably small in-plane displacements at the supports which can change the response from that of an axially restrained beam, with considerable reserve strengthening beyond the limit load for moderate lateral deflections, to that of a freely supported beam with no concomitant increase in strength beyond the limit load. A comparison has also been made between some theoretical predictions for a laterally loaded square plate and the corresponding experimental results obtained by Clarkson on rotationally fixed plates with edges free to slide inwards.
