Reliability based nonlinear fracture mechanics analysis of a concrete dam; a simplified approach
17 March 2006
At a time of decaying infrastructures, and limited resources, there is a need to prioritise rehabilitation by combining probabilistic methods with advanced structural analysis. This paper seeks to demonstrate such an investigation where the safety of an older dam is assessed through its reliability index and a non-linear fracture mechanics based investigation. It is shown that such a complex evaluation is not only possible, but it provides the Engineer with much insight as to what are the key variables affecting the structures safety, and which in turn may warrant additional resources for quantification.
