Abstract: The purpose of this paper is to evaluate the impact factor (IM) in LRFD bridge design specifications for fatigue design and to propose a method for determining reasonable IMs for the fatigue design of steel I-girder bridges ...

Abstract: A finite-element (FE) model of a structure is a highly idealized engineering model that may or may not truly reflect the physical structure. The purpose of model updating is to modify the FE model of a structure in order ...

Abstract: Scour is one of the main causes of bridge failures. It accounts for about 60% of bridge failures in the United States. Scour failures tend to occur suddenly without prior warning and are very difficult to monitor during ...

Abstract: This paper is intended to review the main causes and mechanisms of bridge collapse. The common factors resulting in bridge collapse are first reviewed. These factors are classified into two broad categories, namely, natural ...

Abstract: A method for predicting the bounds of vehicle-induced bridge responses with uncertain bridge and vehicle parameters is presented. The uncertainties in the parameters of the bridge and vehicle are represented with interval ...

Abstract: Expansion joints will experience increasing deterioration and damage under repeating vehicle loading. A severely damaged expansion joint will induce significant dynamic vehicle load effects on the bridge deck near the ...

Abstract: The current highway bridge design in the United States follows the AASHTO-LRFD specifications, which prescribe a dynamic load allowance,

Abstract: With the increasing demand in freight transportation, truck overloading has become a common issue worldwide. Overloaded trucks pose great challenges for transportation administration in that they can jeopardize the safety ...

Abstract: The fatigue damage of steel bridges induced by heavy traffic loads is a critical problem worldwide. A uniform fatigue vehicle is generally adopted in bridge design codes to evaluate the cumulative fatigue damage of steel ...
