本研究針對中空鋼骨鋼筋混凝土扭轉撓曲載重行為進行探討。從扭矩與彎矩之互制作用，探討不同斷面配置與載重偏心距對構件極限強度、勁度衰減、韌性和消能能力之影響。實驗結果顯示，構件之承載能力，因扭矩與彎矩之聯合作用而有顯著之影響。

This study is focused on the flexural-torsional behavior of a composite design composed of reinforce concrete and encased steel tube. Width/depth ratio of cross sections and eccentricity ratio, were chosen as the main parameters for comparisons. Behavior among members'' ultimate strength, ductility, stiffness deterioration and energy dissipation capacity were also studied. It is concluded that the members'' performance is significantly influenced by the interaction between torsional loading and bending moment.
