Shear buckling of trapezoidal web plate

One of the issues raised since the steel structure was introduced in the construction industry is how to reduce the weight and the cost of the component parts such as girder and beams. Economical design of girders and beams normally requires thin webs. But if the web is extremely slender the problem...
