New analytical method for predicting hysteretic moment-curvature relations of cross sections and moment-rotation relations of reinforced concrete members under varying high axial forces are presented. Members are divided into interface elements, sections and fibers. Stress-strain relation of each fiber at all sections are calculated and integrated from constitutive laws of steel and concrete. Predicted moment-curvature relations under varying high axial forces are found to give accurate agreement with empirical results obtained by the hybrid loading system of earthquake response named as HYLSER which is explained in detail in the first paper of the project presented in this symposium. Application of the proposed model to calculation of earthquake response of large scale RC framed structures is presented in the following third paper in this symposium. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
