Abstract
This paper describes a study on shear strength of slender RC beams without shear reinforcement suggested by three shear evaluation methods viz. a proposed shear strength equation based on the fracture mechanics approach and two Indian codes of practice namely IS 456 (2000) and IRS 1997 (2003). 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 design parameters on shear strength of RC beams.
