Abstract: Based on nonlinear FEM method, the author adopt concrete damage plastic model, analyze the structure nonlinear behavior in different load cases, and obtain the occurrence and development of the plastic damage of cooling tower. The analysis reveals that the damage of cooling tower occur at the top firstly and some paralleling damage zones occur at the height of half the tower which will develops 45 degrees downward. The development of the damage will continue until the cooling tower losing bearing capacity. The results is very meaningful for the design of nuclear power plant cooling tower as well as the safety evaluation.
