Abstract

To evaluate the impact behavior and the residual strength of RC protective structure under repeated impact load is essential for building of performance based design method of protective structure.In this study, damage condition of RC beam under single impact load was clarified by using Lemaitre's damage model, which can evaluate stiffness degradation of damaged materials for unloading/reloading. Further, a new cumulative damage model was proposed. By using the model, the residual strength and allowable impact condition were evaluated based on cumulative damage level of RC beam under repeated impact load.
