This study mainly evaluate the aseismic performance of the existing intake tower structure, which is one of the national important infra structures, on the basis of the refined finite element (FE) analysis results. The realistic evaluation for structural damage was conducted by using the nonlinear material model that takes tension and compression strength of deteriorate concrete into consideration during FE modeling. In addition, not only tension crack but also compression crushing was analyzed by utilizing field contour functions provided in the program during nonlinear dynamic analyses when peak ground acceleration (PGA) occurred. After observing FE analysis results, it can be shown that the damage of the intake tower is the most likely to occur at the water level and the base support.
