碩士 === 東南科技大學 === 防災科技研究所 === 100 === This research is to establish an effective and simple method to evaluate the ductility of reinforced concrete (RC) beam sections. This method not only can quickly obtain the curvature ductility ratio of RC beam section, but also can be a basis of the design on section ductility in the future. The first part of this research is to analyze the moment-curvature of 648 RC beam sections under crush limit state, and a semi-empirical equation for curvature ductility ratio and the position of the neutral axis was established. The second part of this research is to discuss the curvature ductility ratio of RC beam under the deformed ultimate state. Then, we establish the relationship of curvature ductility ratio between deformed ultimate state and concrete crush limit state, which can be used to evaluate the curvature ductility ratio of RC beam under the deformed ultimate state.
