Abstract

This work is concerned with the prediction using nonlinear finite element program, of the ultimate strength of reinforced concrete beams failing in shear. Nearly one hundred rectangular beams and a few T-beams were analysed. The beams analysed have been tested by various investigators covering the important variables such as : -a) Shear-span to depth ratio av/d. -b) Amount of shear reinforcement. -c) Amount of tensile reinforcement. -d) Effective depth and width of the beam. -e) Type of loading. The work can be divided into two main parts: 1) Parametric study involving the following parameters: Shear retention factor B. Concrete uniaxial compressive strength fc. Concrete tensile strength ft. Concrete crushing factor Cf. 2) Statistical study involving concrete crushing factor Cf as parameter. The following results were obtained: i) The shear retention factor and concrete tensile strength have little effect on the ultimate load ii) Concrte uniaxial compressive strength and crushing factor both have a great effect on the ultimate load and mode of failure of reinforced concrete beams. From the statistical study it was found that : 1) Generally, smaller the value of Cf, lower the predicted failure load. 2) Better result were obtained for beams with shear reinforcement and for beams with uniformly distributed loads. 3) Concrete crushing factor Cf effect decrease as concrete strength fc' increases. 4) Best results were obtained for Cf = 0. 60 .
