Ang Multidisciplinarias (Ciencias Sociales) cycle cost wind loading expected life optimal design Bridge reliability A highway bridge located inTampico, on the east coast of Mexico, isanalyzed to determine its structural reliabilityagainst wind loading. The inherent variabilitiesof the random wind force and of themechanical properties of steel constitutethe aleatory uncertainty; this contributes tothe probability of failure of the steel girder.The idealization of the loading and of thebridge structure, and the analysis of thestructural response to wind loading, contributeto additional uncertainty of the epistemictype, which leads to a range of possible(or distribution of) failure probabilities.
