摘要：
A model is proposed to analyze the tension-stiffening behavior of RC beams. The model takes into account the constitutive laws of constituent materials and the bond-slip relationship at the steel-concrete interface so that reliable responses of the RC beams in the post-cracking range can be obtained. It also allows the local behavior of RC beams to be studied in details due to the bond interaction between steel and concrete. Finally, the model capabilities are employed to analyze own experimental results. The midspan deflection and the mean steel strain of RC beams, computed with the proposed model, seem to be in good agreement with those measured in the tests.
