Probability modelling of shear strength parameters of RCC gravity dams for reliability analysis of structural safety [PDF]
European Journal of Environmental and Civil Engineering, 2009 Modelling concrete shear strength is the main difficulty in probabilistic reliability analysis of gravity dam structural safety. The main reason arises from the lack of test data on the parameters. This paper proposes a procedure for probability modelling of Roller Compacted Concrete (RCC) gravity dam shear strength based on all tests performed during ...
