Shear Strength Models for Reinforced Concrete Slender Beams: Comparative Analysis and Parametric Evaluation

Shear failure of reinforced concrete (RC) members belongs to brittle and has always been concerned. In this paper, 16 existing shear strength models RC slender beams have selected comprehensively compared based on a set 781 experimental test results. These formulas from eight national codes published papers are mainly the semi-empirical or analytical models. results were collected 66 papers, range key parameters is relatively wide. The accuracy these evaluated overall prediction level effect parameters. contain compressive strength, shear-span-to-depth ratio, effective depth, stirrup ratio. According evaluation parameters, Zsutty’s, Gunawan’s, Bazant–Kim’s more accurate than others for both with stirrups without stirrups. ACI JSCE exhibit higher safety margin, their average values between 1.19 1.28. study may provide reference selection and/or improvement model beams.
