Recently, Korea design codes about CFT columns were indicated. Such are the Specifications and Codes for Allowable Stress Design by Korean Society of Steel Construction in 2003 and Korean Building Codes for Limit State Design by Architectural Institute of Korea in 2005, which was revised in 2009. However, KBC/LSD provision underestimate the strength of CFT columns. Therefore, more accurate estimation of strength of CFT columns is needed. Current research performs column tests under eccentric axial load and investigates buckling loads of the columns in inelastic range. It also compares the test results to KBC/LSD provision. This paper suggests new design method of CFT columns for KBC/LSD provision.
