This paper analyses the curvature distribution characteristics of reinforced concrete members with flexural and compressive axial load, simplifies the curvatures in two working levels on half-span with bilinear and trilinear distribution, and deduces formulas for determining the boundaries between two adjacent regions.The method presented is suitable for hand computation of the ductility factor of structural members, By the proposed formulas and method, 24 reinforced concrete members with flexural and compressive axial load have been analysed and satistactory results have been obtained. Based on the experimental and theoretical analysis, this paper also demonstrates the reasonable value adopted for ultimate strain of concrete and considers that it is sensible to take eu= 0.003 for ductility analysis of unconfined reinforced concrete members with flexural and compressive axial load.
