摘要
To study the first cracked stage in R/C members in tension or bending two monodimensional models are proposed. The models analyse the transition from the pre-cracked stage to the post-cracked one by assuming a bond-slip relationship and one cohesive crack. The accuracy of these assumptions is checked by comparing the numerical results with some experimental data. The models are used to compute the minimum reinforcement ratio and to enlighten its size-effect.
