This paper proposes the framework of detailed damage assessment of RC frame structures subjected to reversed cyclic loading based on the damage and failure of constitutive materials, which can be applied, in the future, to the safety and repairability verification of RC structures. The evaluation scheme based on the spatially-averaged strain-based indices incorporated to the damage of constitutive materials, which are calculated from the local stresses and strains at each integration point in the finite elements, are verified for nine RC column specimens fail in shear and flexure. Furthermore, the damage level and deterioration process upto failure of RC frame structures are fully evaluated using the verified method, by conducting the nonlinear finite element analyses of 1- and 2-layer RC frame and RC box culvert specimens.
