Abstract

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