Abstract:

 

Reliability-based assessment of local scouring mechanism around bridge  piers provides information for decision-making regarding the pier footing  design.  Parameter uncertainties that may arise from various sources  due to the inability to precisely quantify a parameter need to be  estimated in order to quantify the level of risk of pier failure during the  physical life of a bridge.  By examining extensive experimental data  from the literature   on local scour depth around various shapes of bridge pier   the functional dependence of relevant parameters is  examined.  The degree of uncertainty and the statistical  randomness of these parameters are assessed in terms of coefficients  of variation and probability distribution functions, respectively.
