Strength reduction factor for flexure
WebThe strength reduction factor for a concrete section controlled by flexure is 0.9 where for shear it is 0.75, what is best explanation for the reason between the different factors. O Shear reinforcement (stirrups) are cheaper than longitudinal reinforcement hence we can afford a larger strength reduction without substantially affecting the cost. http://www.ce.memphis.edu/4135/PDF/Notes/Chapt_5_3.pdf
