要旨 The aim of the present study is to discuss the strain gradient effect on tension stiffening of reinforced concrete members under flexure and/or axial loads. The analytical model is derived from the micro-bond characteristics. The local steel strain and stress are computed from which the average moment-curvature relationship is derived. The average crack spacing is simply computed by a stressbased cracking criterion. A comparison with experimental observations was carried out to verify the effectiveness of analysis. The analysis fairly agrees with the experimental results.
