Aging concrete dams require careful evaluation beyond standard static checks. This session presents a practical case study of a 100-year-old concrete arch gravity dam in Australia, focusing on how static, thermal, and seismic effects were assessed through finite element analysis using MIDAS FEA NX.
The session will walk through the modelling approach, including dam–foundation interaction, unbonded lift joints, vertical contraction joints, seasonal thermal variations, and nonlinear time history analysis. Participants will see how engineering investigation data, load combinations, stress results, displacement behavior, and sliding stability checks are brought together to evaluate the dam’s structural integrity and long-term safety.
