166320 hypothetical reinforced concrete (RC) columns, each with a differentcombination of variables, were used to investigate the major variables that affect theflexural rigidity (EI) of slender RC columns. Using linear regression analysis, new EIexpression was statistically developed for 131 slender RC columns. These columns wereexperimentally tested and available in the literature. This proposed EI expression wereintroduced into the ACI 318M-05 Code column design procedure to make comparisonsbetween 150 column experimental data with theoretical estimates of the nominalstrength using theoretical other methods. These estimates include, in addition to the proposedEI expression, other calculations from the literature.
