Using Sensitivity Studies to Evaluate a Concrete Arch Dam

ANSYS DesignXplorer VT helps to reduce project cost and provides engineers with insight into structure behavior. In evaluating the dam, URS engineers performed sensitivity and parametric studies using ANSYS DesignXplorer VT to assess the influence of a range of variables on structural strength, including concrete wall and foundation rock material properties as well as maximum load assumptions. Results from the sensitivity studies using ANSYS DesignXplorer VT quickly showed that the behavior of the dam was influenced by foundation strength assumptions more than any other parameter.
