95 Reliability Analysis of Scouring around the Bridge Abutments Niloofar Mahinparvar Niloofar mahinparvar@gmail com Date of Submission Jan 23 2015 Department of Civil Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor Phd Abdorreza Kabiri Samani akabiri@cc iut ac ir Advisor Phd Amin Salamatian amin salamatian@gmail com AbstractAmong all the reasons for the bridge breakdown scouring is the biggest danger To reach the appropriate level ofsecurity and reliability for a bridge its breakdown risk needs to be calculated In this research to expand the riskassessment application in the bridge safety reliability the bridge abutment scouring equations are assessed for theirreliability based on the probability distribution of the effective parameters in those equations These parametersinclude channel shape abutment shape sediment and stream flow To evaluate each equation s breakdownprobability Monte Carlo analysis is used and reliability index of each equation is going to be compared In theconclusion among the equations the equation with the least breakdown probability and higher index of reliabilitywill be chosen as the appropriate equation In addition the results show that the uncertainty of the parameters shouldbe included in the bridge abutment scouring Among those parameters uncertainty in depth and flow speed has themost dominant effect in the bridge abut scouring KeywordsUncertainty Risk Analysis Scouring Bridge Abutment Monte Carlo Simulation
