장경간 케이블교량 설계를 위한 활하중 재하 방법에 관한 연구

Due to Increasing demand of the domestic long span bridges, cable bridge design guidelines are being developed. This paper deals with the influence line analysis of live load model for long span bridges reflecting truck traffic characteristics in Korea. In case of cable bridges such as cable-stayed bridge and suspension bridge, there may be cusped or intermittent influence lines. In this case, various influence line length can be considered. live load model presented in a previous study calculated as the ratio of maximum value of the influence line. In this study live load effects from considering various influence line length are analyzed and compared for main members and forces.
