摘 要：The robustness analysis is conducted from the viewpoint of energy. A new method to robustness appraisal is developed, in which a dimensionless form of the amount of energy that the structure absorbs serves as a robustness index. A flexural member is adopted for illustrative purpose. Furthermore, the relationships between the robustness index and the ratio of ultimate strain to yield strain of four typical members are defined. It is shown that the index proposed herein can reflect the influence of member behavior in terms of robustness. Finally, methods of ensuring structural robustness are discussed.
