Abstract
The extensive study of flexural behaviour of R.C beams has clarified mechanisms to such an extent that its verified outcome is already incorporated in many codes. Progress in the understanding of the behaviour of beams also subjected to shear has not been quite as spectacular. Notwithstanding many decades of experimental and theoretical research, shear failure is not yet fully understood. No rational theory exists for shear strengths, but continuing research is refining proportioning and detailing of structural concrete members for shear. Though design codes specify the maximum permissible spacing limits of stirrups legs span-wise, they are silent on the beneficial refining of stirrup spacing along the span, resulting in marginal strength increase and significant reduction in deformations. Codes are also silent on the location of stirrup legs width-wise in wide beams. The current research focuses on detailing stirrup reinforcement along the span as well as width of an R.C beam. The requirement and refinement of stirrup spacing in beams is interpreted by truss model.
