Abstract
Based on the observation of the formation of flexure-shear crack and web-shear crack, and the occurrence of flexure-shear failure and web-shear failure, approximate analytical expressions to predict the shear force at cracking and failure have been developed based on assuming physical models. The validity of these expressions has been examined by comparing with experimental data, and best-fit semi-empirical equations have been developed. The experimental data consisted of a total of 221 rectangular specimens tested under four point loading. Of these, 155 specimens were reinforced with wire meshes uniformly distributed in the thickness or lumped equally at top and bottom and 66 specimens with wire meshes and steel bars. The proposed semi-empirical equations are then compared with the predictive equations available in the literature. Characteristic shear strength equations also corresponding to the semi-empirical equations are proposed. In respect of those specimens failing in shear, the shear strength has also been calculated using available ACI and BS code procedures for reinforced concrete and compared.
