Abstract: A general method of plastic analysis and a procedure for the proportioning of non-prismatic members composed of symmetrical sections and subjected to proportional loadings has been developed. Plastic hinges are classified in terms of their location in order to facilitate the analysis. By using approximate hinge locations and repeated iterations, the actual hinge locations may be determined and the collapse load evaluated. The plastic design of a non-prismatic member consisting of a web and two flange plates involves several parameters which have been related. Design charts have been prepared that will enable a haunch of minimum weight to be selected for any specified loading.
