摘要：

In order to overcome the disadvantages of traditional modes which cannot take into account the influence of axial load ratio and need to introduce empirical corrected factor of displacement ductility, an improved shear strength model for shear-critical reinforced concrete (RC) column was proposed. Firstly, an improved shear strength model for RC columns which takes into consideration the influences of axial load ratio as well as the deformation compatibility condition of variable angle truss-arch model was established based on the critical crack angle model that takes into account influence of axial load ratio as well as the deformation compatibility condition of the variable angle truss-arch model. Then the influence of axial load ratio on the shear strength of shear-critical RC columns was discussed. The proposed model overcomes the disadvantages of traditional models. Finally, the applicability and accuracy of the proposed model were validated by comparing with the experimental data and existed models. © 2018, Editorial Office of Journal of Vibration and Shock.
