Abstract

This paper investigates the potential effects on European bridges of the introduction of long combination vehicles (LCVs) into Europe's truck population. Measurements of actual truck traffic have been collected at a number of sites throughout Europe using Weigh-In-Motion (WIM) technology. With knowledge of the traffic at a site, a traffic loading model can be tailored for a bridge at the site. Monte Carlo simulation based on this traffic loading model is used to predict the likely load effects that a bridge will expect to carry over its design life. By modifying this model to allow for LCVs, this paper examines the potential effects on the lifetime loading on bridges. It is concluded that the introduction of LCVs is not expected to impact on the lifetime load effect for which a bridge must be assessed. This is because shorter, heavier vehicles, such as cranes and low-loaders, are found to govern extreme loading events.
