Abstract
This chapter discusses in detail the way a general-purpose finite element code can be employed to predict the lateral distribution of vehicular live loads on bridge girders effectively and efficiently. Longitudinal girder is a vital component of a bridge structure. In designing and constructing bridge girders, a critical issue concerning bridge safety and economy is to properly figure out the lateral distribution of vehicular live loads on them. Because vehicles are randomly positioned and moving on a bridge, the determination of proper live load distribution is a formidable task. The governing design code—i.e., American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications, permits the designers to use empirical formulae to predict the live load distribution.
