A ductility index, which effectively represents the ductile behaviour of a  reinforced concrete member, has been established. This ductility index is  named as limiting ductility factor.  A mathematical model, in the form of a damage model, has been  established as a result of this study. The proposed model can be used to  calculate the limiting ductility factor and corresponding number of cycles for  a cantilever type reinforced concrete member subjected to any type of loading  history with fully reversed loading cycles.  The development of the model is based on theoretical, empirical and  logical concepts. The proposed model gives results in appreciable agreement  with the previously existing experimental data and confirms the conclusions  drawn by previous researchers. 0aReinforced concrete construction1 aUeda, Tamon, eChairperson1 aWireland, Martin, eExamination Committee0 aPichai Nimityongskul,eExamination Committee1 aJain, Sudhir K., eExamination Committee2 aRoyal Government of Netherlands, eScholarshi[ Donor2 aAsian Institute of Technology.tThesis ;vno.
