Consideration of Slenderness Effect in Columns

Due to the fact that a reinforced column is a non-homogeneous member consisting of steel and concrete and concrete is subjected to creep and shrinkage while steel is not, it is not easy to find EI exactly. If we try to do an exact analysis to find the EI, the value we find will be as good as our assumptions. ACI Section 10.12.3 say: 0.2 1 cg S
