Stress Diagram For Singly Reinforced Beam. Practically for singly reinforced beams two additional bars are supplied in the compression face of the beam so that stirrups can be tied with bars easily. Follow my facebook page.

T he figure given below shows a typical section of singly reinforced concrete beam with strain distribution and equivalent stress distribution proposed by whitney. Reinforced concrete beam sections in which the steel reaches yield strain at loads lower than the load at which the concrete reaches failure strain are called under reinforced sections. Every singly reinforced beam should be designed as under reinforced sections because this section gives enough warning before failure. Practically for singly reinforced beams two additional bars are supplied in the compression face of the beam so that stirrups can be tied with bars easily.
