| Abstract: |
This paper deals with the development of live load model for long span bridges. New live load model reflects truck traffic in Korea using Weigh-In-Motion system that was installed on the road with the heaviest truck traffic volume. By using collected WIM data, various truck traffic scenarios are assumed. To analyze the load effect, typical long span bridge such as a suspension bridge and a cable stayed bridge are modelled. Based on traffic scenarios, equivalent uniformly distributed load are calculated and loaded to the selected bridge. The results of load effects are compared with other load model in internationally renowned design code such as AASHTO LRFD, Honshu-Shikoku bridge design code and existing Korea Bridge Design Code. Based on the results of analyses, new live load model for long span bridges is proposed. |
