ABSTRACT
Since the most of the contemporary ultimate shear load capacity formulations are based on the correction of the calculated elastic shear buckling critical stress, within the framework of this paper various possible approaches to the elastic shear buckling inhibition are discussed. The most obvious one among them is to maximize the rotational restraint along the plate edges, resulting ultimately with the clamped edge restraints. However, the actual edge restraint imposed at the plate edge joints varies between the two extreme cases (simply supported and clamped). Only the worst (simply supported) case, which provides the highest margin for the increase of the plate elastic shear load capacity, is considered further in this paper.
