Single Web Shear Element Model for Shear Strength of RC Beams with Stirrups
Abstract In this paper, an analytical model to rationally evaluate the shear strength of reinforced concrete beams with stirrups has been developed. In the developed model, a shear critical section has been idealized with a single web element for shear and the top and bottom chords for flexure, resp...
