The reduced stresses in the longitudinal bars help to achieve less critical bond condition under the cyclic loading, especially in the lack of column axial force.
降低了的梁内纵筋的应力能在反复循环荷载下获得较为有利的粘结条件，特别是在缺少柱上轴向压力的时候。

The numerical results show that Bar-scale model with radial elastic modulus of bond interface is significant for the radial performance or not for the axial performance.
