With the calculation methods for the sectional curvature ductility of reinforced concrete flexural components, analysis was conducted on the factors affecting the formation of plastic hinges at the ends of RC frame beams and their rotational capacities; on the basis of which, singly-doubly reinforced rectangular section method for flexural design calculation was put forth, which is favorable to the realization of beam hinge mechanism. The analysis of a practical design case shows that the method proposed is not only beneficial to the formation of plastic hinges at the beam ends and their rotational capacities, but also results in considerable reduction of longitudinal reinforcement, hence lowering of cost, ease of construction, so that it is worthy of popularization and application in design practice.
