ρ=0.85fc′fy(1−1−2Rn0.85fc′)rho equals the fraction with numerator 0.85 f sub c prime and denominator f sub y end-fraction open paren 1 minus the square root of 1 minus the fraction with numerator 2 cap R sub n and denominator 0.85 f sub c prime end-fraction end-root close paren Verify that falls between the minimum steel ratio ( ρminrho sub m i n end-sub ) and the maximum tension-controlled steel ratio ( ρmaxrho sub m a x end-sub ) defined by the code. Calculate Steel Area ( Ascap A sub s ): Find , then choose the number and diameter of reinforcing bars.
