An Improvement for Evaluating Load Carrying Capacity of Long Span Bridge with respect to Passing Vehicles

통행차량에 의한 장대교량의 내하력 평가기법 개선

This paper presents the development of a method for determining the response modification factor, using traffic load. The proposed method is based on the results of computer simulations of traffic action effects. The simulation program generates random traffic actions for defined traffic conditions and determines the frequency distribution of maximum traffic action effects. Therefore, this study is adopted to long-span bridge for the verification of the proposed method. A comparison between the proposed method and present method shows good agreement in estimating the modified load carrying capacity of bridges.
