Abstract

Abstract

To analyze characteristics of typical parameters of overloaded trucks as well as their models, weight-in-motion (WIM) data was collected over three years from California, U.S., and the permit truck issued by California Department of Transportation (Caltrans) was selected as a reference to extract overloaded truck data, then, the characteristics and configurations of these overloaded trucks were analyzed to build typical overloaded truck models with mean and standard deviation calculated. In addition, load effects induced by trucks moving on multiple lanes and single lane were calculated respectively, and the two load effects were compared with the specifications issued by the Ministry of Transport of China (JTG D60−2015) and American Association of State Highway and Transportation Officials (AASHTO) respectively. The results show, superposed load effects on multiple lanes were significantly greater than those loading on one lane and the codified values in specifications, whereas, the load effects on one lane are close to or a little higher than the specified values. For effect ratios of multiple lanes to one lane, the largest one is 2.05 for both moment and shear, and the average value is 1.65 and 1.70 for the two, respectively.
