EVALUATION OF SHEAR STRENGTH OF SLENDER RC BEAMS WITHOUT SHEAR REINFORCEMENT

Chidananda G, Raviraj S

Abstract: This paper describes a study on evaluation of shear strength of slender RC beams without shear reinforcement by considering three shear evaluation methods viz. a proposed shear strength equation based on the fracture mechanics approach and the two standard codes of practice namely IS 456 (2000) and ACI 318 (2014). Four hundred and fifty eight test beams selected from ACI– DAfStb database (2013) are considered for the study. The statistical analysis and demerit points classification indicate the proposed equation to show better estimate of shear strength of the test beams. Also the proposed equation captures well the influence of parameters affecting the shear strength of RC beams.
