Reinforced concrete beams are studied in this paper, a nonlinear analysis program is built based on plane cross section assumption to analyze singly reinforced beams with different steel ratios and doubly reinforced beams with identical tensile steel ratio and variant compress steel ratios to get their M-φ curves. Finally, the influences of reinforcement ratios and compress steel arrangements on both the ductility and bearing capacity of reinforced concrete beams are discussed.
