Shear Strength Equation for High-Strength Concrete RC beams with High-Strength Stirrup

摘要

In this investigation, test results of 102 high strength concrete (HSC) beams and 76 normal strength concrete (NSC) RC beams with stirrups are collected from literatures to study the shear property based on the modified compression field theory (MCFT). Equations of angle inclination θ of principal compressive stress and average stress f_(v,m) in the stirrups at maximum shear force are regressed according to the analysis results of MCFT, and then the shear force equation of stirrup contribution V_s for these beams contained by θ and f_(v,m) is established.
