| 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. | ||
