Direct analysis method was introduced into Korea as analysis method for stability design of steel frames with the revision of Korea building code in 2009. Direct analysis method includes the effect of initial imperfections and inelastic behavior of members. In addition to these merits, the effective length factor, K, of all members shall be taken as unity. Therefore, AISC 360-10 presents direct analysis method as prototype of stability analysis method. However, direct analysis method has not been widely used in Korea because of limitation of useful information for practice. Thus, it is suggested in this paper that the efficient way of using direct analysis method and the updated items of direct analysis method in AISC 360-10 comparing with KBC2009.
