It is necessary to prepare Moment-Curvature (M-φ) relationship for the analysis of ultimate strength and rotational capacity of reinforced concrete (RC) members. Since no appropriate figures and tables have not yet been available in use to obtain this M-φ relationship, computational efforts are required to analyze complicated stress distributions in members, by taking non-linear stress-strain relationships of concrete and steel bars into account. It has been known that in addition to these material nonlinearlity, cross sectional area ratio of steel bars to concrete body, compressive strength of concrete and arrangement of steel bars also have great influences on the characteristics of M-φ relationships. This paper concerns with parametric analysis for M-φ relationships for RC beam members and M-φ-P curves for RC columns.
