Title: Economy and Concrete Beams

Abstract:Relationships and charts ae presented fom which may be readily determined the cross-sectional dimensions for maximum economy of materials for a beam or slab with given span or loading. Whitney's theory is used to express beam strength. The steel saving possiblities of economical dimensioning are considered and found especially important. This optimum dimensions almost never correspond to balanced design, but depend on relative material costs, relative material strengths, relative length of beam reinforced for diagonal tension, and relative importance of beam dead weight. Optimum dimensions for the Whitney theory also serve as a general guide to efficient design by the elastic theory.
