This report presents the work done during the the CUREe-Kajima research project "Hysteresis Modeling of Reinforced Concrete Bridge Members Subjected to Combined Loading". Two major tasks are addressed in this report:
- the verification of the fiber model for modeling the hysteresis of reinforced concrete columns subjected to bilateral loading and varying axial load, and
- the development of an improved stand alone cross-section analysis program, ArcS.
The report concludes with a summary of the results achieved and outlines of research opportunities arising out of this project.

There may be aseismatic design concept in which the verification of the energy absorption of the structure is intended against an earthquake having an intensity greater than the design earthquake. In this case, a non-linear earthquake response analysis of the structure is needed and sometimes a bidirectional earthquake response analysis is performed.
For the purpose of application of fiber model analysis for simulating the relationships between the bending moment and curvature of the reinforced concrete tower members (longitudinal steel ratio of 0.95%, compressive axial force of 80 kg/em ) of cable-stayed bridges under biaxial bending, suitability of fiber models were investigated by paying attention to the reinforcing bar model. Biaxial bending tests were performed on the RC-column specimens having rectangular cross section and the simulation analysis were performed on these specimens by using fiber model.
