本文旨在探討配置不對稱縱向鋼筋量之梁受到彎矩和扭矩組合載重作用下之承力行為。本研究共規劃8根350 �e 500 mm之矩形斷面鋼筋混凝土梁試體，全長約為3100 - 4400 mm，在相同配筋條件下，分別承受不同彎矩加扭矩組合載重作用，主要討論之變數為扭矩和彎矩比值(T/M)。
研究結果顯示，在組合載重中，試體表面應變受彎矩所造成的正向應力影響較大，且第一類破壞模式之試體側面裂縫寬度隨T/M比值的增加而減小；第二類破壞模式之試體側面裂縫寬度不隨T/M比值而有明顯趨勢，平均主張應變、裂縫數目及平均裂縫間距，與局部量測之裂縫寬度有合理的關連性。此外，當試體之破壞模式轉換時，最大平均主壓應變發生面亦隨之轉換，且所有試體之底面平均主張應變較其他三面大。
