Abstract


The reinforced concrete member has good ductility is guaranteed structure having better ductility premise , study the ductility has important significance . Countries researchers a lot of analysis of the factors affecting the ductility , summed up the relationship between the various factors with ductility and proposed measures to ensure that the member has good ductility . However, to ensure that the member has certain requirements of the ductility of reinforced elongation and ductility of the existence of the size effect than less. Theoretical analysis and collected on the basis of a large number of test data , the paper analyzes the Single Rectangular Double Reinforced Rectangular T -shaped cross-section suitable reinforcement beam reinforced elongation requirements , in accordance with the basic assumptions of our design of concrete structures derived curvature ductility coefficient formula and displacement ductility factor formula proposed in order to ensure the section has a curvature ductility factor and component to some displacement ductility coefficient for reinforced elongation requirements , summarizes the national researchers proposed reinforced concrete flexural members and bending component equivalent plastic hinge length calculated equivalent plastic hinge length size effect exists . In addition, this paper summarizes the impact ductility factors as well as to ensure that the member has some ductility countries norms measures taken . Finally, the conclusion of this study work , summarize and future research directions are discussed .
