ABSTRACT

This paper discusses the methodologies, analytical concepts and the statistical models derived from the analysis of a 10-year WIM database described in (Miao 2001). The statistical analysis approach used in this paper is an effective method to obtain the Cumulative Distribution Function (CDF) of related parameters such as gross vehicle weight, axle weight, axle spacing and so on. These obtained parameters are the base of formulating the bridge live load models (Miao and Chan 2002). This approach can provide a distinct CDF and a required value of any parameter under a given probability level.
