Cassells, Ryan UCTD Sustainable Development Goals (SDGs) Arch dams Numerical modelling of dams FEA calibration Monitoring of arch dam behaviour Sensitivity analysis Dissertation (MEng (Structural Engineering))--University of Pretoria, 2025. Concrete arch dams are complex three-dimensional structures, the design of which requires an iterative structural analysis approach to ensure the most efficient arch is adopted for site conditions. Due to a significant increase in computing capacity over the past two decades and economic viability of user-friendly numerical modelling software packages, advanced numerical modelling has become the current state-of-the-art tool for concrete arch dam design. Structural analysis of concrete arch dams using finite element modelling, can provide valuable insight into dam function and behaviour for evaluation against design criteria and probable failure modes. Finite element analysis results, are however, only as reliable as the model input assumptions and material parameters of the dam. Considering this, it is critical to validate assumed finite element modelling parameters, by calibrating the modelled behaviour according to the actual measured behaviour of the dam under loading. This dissertation investigates the derivation of a calibrated finite element model of a super-high concrete arch founded on complex foundations, from which various behavioural and sensitivity analyses outcomes are formulated.
