Abstract：Damage and Crack were the key factors that affecting the dam’s safety under seismic excitation. Take Koyna arch dam as example, two different forms of seismic reinforcement schemes are presented. According to the plastic-damage concrete damage model, and based on the embedded model of reinforced concrete, the seismic responses of concrete gravity dam are calculated under different reinforcement schemes. The results verified the necessity and practicality arranging reinforcement for seismic resistance at the weak parts of the dam.
