Based on the study of bridge live loads and traffic modes for using WIM datas, it was found that the structural integrity of bridges was damaged by overloaded heavy vehicles. The objective of the study is to investigate the statistical characteristics of vehicle loadings based on survey data collected, in which some major factors, such as vehicle configurations, vehicle weights, traffic modes, etc., are incorporated. The vehicle load effects due to single presence of heavy truck are also tested with several short- span bridges and probabilistic characteristics of current design practices are evaluated.
