Abstract:
Section 10.11.3 of the 1971 ACI Building Code requires that the effective length factor k for slender concrete columns be determined with due consideration of cracking and reinforcement on relative stiffness. The reasons for this requirement are outlined and a calculation procedure is proposed which results in acceptable accuracy.
