The significance of correctly applying water-related loads, including hydrostatic and hydrodynamic forces, pore water pressure, uplift pressure, and wave pressure to a concrete dam wall are discussed in the paper.
Pine Flat Dam in the United States is studied to identify the effects of modelling the water load over the valley floor in the behaviour of the concrete dam. The static and dynamic behaviour of the dam subject to 9 different seismic events is reviewed. A nonlinear elastoplastic material model was employed to determine the damage to the dam wall. The results show that when the water load acting on the valley floor is added to the model, the downstream displacement of the dam crest reduces, and the tensile stresses in the dam wall increase, although the compressive stresses are reduced. In some earthquake events, the damage pattern has changed from more damage downstream in the no water load modelling to upstream in the water load modelling. This change in the damage pattern can affect the safety assessment of the dam.

System maintenance will be performed on the servers that host the ANCOLD Digital Guidelines, on Saturday, December 21st @ 10:00 PM AEDT which will require the servers to reboot.
Total downtime during that event could be up to 4 hours and will commence sharply at 10 pm AEDT. During that time end users will not be able to view or access their secured content.
