This paper examined a local index to use as failure criterion for RC beams in nonlinear finite element analysis. First, the requirement for local index such as mesh size independency was discussed. Then, local element deformation of a localized element in compression zone was proposed as the local index. Moreover, the value of the local index was proposed to evaluate maximum load point. The applicability of proposed index was verified by analyzing RC beam failed in shear and flexural behavior and the reasonableness was conformed.
