... or foundation. Furthermore, the climate change implies that the probable maximum flood (PMF) can be expected to increase, which puts higher demands on the dam to sustain loads. In addition, assessing the current safety of an existing dam is many times more difficult than ensuring that a dam-to-be-built...

In addition, it discusses how partial factors are calibrated from RBD and how code development can...

... 2009) Probability is such kind of method to solve problems related to a random data. Recently uncertainties and risks should be expressed in the language of probability and that calculations of risk should be based on inferences made using statistics (Baecher & Christian 2003). The mechanical...

Based on observations made in the construction site after the failure occurrence, the failure mode has been diagnosed as localized slip over interbedding plane at the interface. A relatively simple method for determining the failure probability has...

With a Bayesian approach, one expresses the degree of belief that something will happen, instead 1435 of interpreting probability as strictly frequentistic, see e.g. Christian (2004).
