The investigation attempts to establish minimum weight beam proportions, based on beam web elastic buckling criteria, for unstiffened I beams in pure bending. The investigation is basically a study of the parameters affecting beam weight for both strength and deflection designed beams. It is shown that an optimum beam depth exists at which the beam cross sectional area will be minimum for both strength designed and deflection designed beams. Design charts are prepared which enable the beam designer to select the lightest weight beam depth for the design moment load and for the design stress level that the beam can sustain.
