The behavior of reinforced concrete columns subjected to uniaxial reversal loading and biaxial reversal circle path loading was investigated. Four full scale test specimens were tested. Two kinds of hoops arrangement, of 0.6% and 1.2% by transverse reinforcement ratio, were used. It was found that ductilities in biaxial loading were smaller than those in uniaxial loading. The maximum strength and the drift angle at maximum strength were almost the same under uniaxial and biaxial loading. The specimens of ratio of transverse reinforcement of 1.2% exhibited better response than those of Q.6% both for uniaxial and biaxial loading. Inelastic moment curvature relations under uniaxial and biaxial loading could be analyzed by fiber element model analysis method. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
