The bar arrangement method of the column whose hoops were simplified was developed on the grounds that the outer steel plate of RC columns was effective in increasing the bond splitting strength of the main bars which were arranged at the outer side in the direction of column width. The test of RC columns with steel jacketing was carried out in order to verify structural performance. As a result, the shear strength did not decrease even after the yield hinges were formed. Furthermore, there were not many cracks in the column with steel jacketing at the final loading. This performance of the column with steel jacketing did not depend on the type of bar arrangement on condition that the amount of lateral reinforcement was the same. In this paper, both the equations for ultimate strength and load-displacement relation that correspond to the destruction pattern for RC columns were showed.
