FAQ

What is Area of Steel Required in Vertical Stirrups?
The Area of Steel Required in Vertical Stirrups formula is defined as the amount of area of steel needed to resist the shear force and is represented as As=(Vs*s)/(fy or Area of steel required=(Nominal shear strength by reinforcement*Stirrup Spacing)/(yield strength of reinforcement*Centroidal distance of tension reinforcement). Nominal shear strength by reinforcement is the strength or capacity of shear reinforcement to withstand shear or diagonal stresses, Stirrup Spacing is the approximate minimum spacing between two bars in a section, Yield strength of reinforcement is stress at which a predetermined amount of permanent deformation occurs and Centroidal distance of tension reinforcement is the distance measured from eternal fiber to centroid of tension reinforcement.
