Evaluation of shear design procedures for reinforced concrete beams without shear reinforcements

Abstract

Many structural concrete beams have been constructed without transverse reinforcements. The main objective of this paper is to review design procedures for slender beams. Five major codes namely: ACI, CSA, BS, Australian, Japanese and a procedure based on Shear Friction are considered. More than 500 slender beams without transverse reinforcements which have been exhumed from literature were used for the evaluation. Parameters influencing the accuracy of each and every procedure were studied using a Multinomial Logistic Regression Analysis.
