Capacity Models of RC Column Specimen: Shear Capacity Total shear capacity of an RC column depends on the shear capacity of the concrete, V C and the shear capacity carried by the transverse reinforcement, V ST in the column V N = (V C + V ST ) = 2*[1+(P/2000*Ag)]*√f C ’*b W *d + [(4*A ST *f YT *d)/s] ..where A ST is the transverse reinforcement area, f YT is yield strength of transverse reinforcement, d is distance from compression fiber to farthest tensile reinforcement, s is transverse reinforcement spacing, b W is the width of column x-section, P is axial load V N = 2*[1+(10,000lb/(2000*35.12in 2 ))]*√(3000psi)*(6in)(5.145in) + (0.01228in 2 )(70,000psi)(5.145in) V N = 8.283 kips
