The ultimate goal of the studies reported has been to review, for the purpose of attaining the efficient earthquake-resistant design (EQRD) of structures, the use of the concepts of ductility, ductility ratio, drift, and interstory drift index, and then to identify the research, development, and educational needs required to improve the effective use of these concepts. The report is divided into seven chapters: (1) Introduction; (2) The needs for ductility and drift control and their proper use in establishing reliable EQRD criteria; (3) State-of-the-practice and state-of-the-art of EQRD of RC (reinforced concrete) structures; (4) State-of-the-practice: review of codes; (5) Summary of state-of-the-practice on ductility and drift-based EQRD; (6) Research, development, and educational needs; and (7) Summary, conclusions, and recommendations.
