Excerpt from Tests of Reinforced Concrete, Beams, Vol. 6: Resistance to Web Stresses Series of 1907 and 1908 In the analysis of beam action, two classes of stresses are considered; (1) the horizontal or longitudinal component stresses (tension and compression) which are used in the calculation of the resisting moment of the section, and (2) diagonal, vertical, and horizontal stresses, like shear and diagonal tension and dia gonal compression, which constitute what are frequently termed web stresses. The first named stresses and the resisting moment resulting therefrom in many cases measure the ability of the beam to carry the required load. With reinforced concrete beams, however, the second type of stresses under conditions which are not unusual, may be the limiting element in the strength of the beam, and the resistance to such stresses therefore constitutes an important feature of a well designed beam. These web stresses may include bond stress (resistance to slip of reinforcing bar in the concrete), shearing stresses in various directions, and tensile stresses and compressive stresses in directions other than that parallel to the axis of the beam. The calculation of the amount and distribution of the web stresses is complicated, and for use in design it will be convenient to use certain assumptions and approximations. The discussion will be made under three heads: (1) Beams without Web Reinforcement. (2) Beams with Bars Bent Up, and (3) Beams with Stirrups.
