Analytical model for the ultimate shear strength of reinforced concrete beams

In this paper, based on the analysis and study on analytical model and experimental data available for shear strength of reinforced concrete members, a new theoretical and analytical model for shear resistance capacity is investigated. In the presented new analytical model we apply plastic theory and the softening effect of concrete under cracking state is taken into account. In addition, on the basis of theoretical analysis, the formulas of ultimate shear strength of reinforced concrete beams under concentrated load are established. The calculating results of more than 100 investigated beams by means of the present method show that the calculating results are well agreed with the experimental results.
