The Dynamic Behavior Properties of Concrete Dam for Seismic Magnitude

It was performed that the seismic response analysis using seismic magnitude and concrete dam type(Model-1, Model-2) on dynamic behavior properties of concrete dam. As a results of each seismic magnitude acted on concrete dam, the maximum response acceleration at dam crest was amplified about 3, 5-4 times and maximum displacement and stress at dam crest of Model-2 was larger than Model-1. So, it can be recommended that codified-seismic coefficient method is proper in case of seismic design of concrete dam and Model-1 is better than Model 2 in consideration of stability in displacement and stress of design of concrete dam.
