  • Bridge load rating calculations provide a basis for determining the load carrying capacity of bridges. Load rating requires engineering judgement in determining a rating value that is applicable to maintaining the safe use of the bridge and arriving at posting and permit decisions. Load testing is an effective means in calculating the rating value of bridge. In Korea, load carrying capacity of bridge is modified by response modification factor that is determined from comparisons of measured values and analysis results. This paper presents the development of a method for determining the response the modification factor, using traffic loads. 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. A comparison between the proposed method and the present method shows good agreement in estimating the modified load carrying capacity of bridges.

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.

  • 재하시험은 교량의 내하력을 측정하는 효과적인 방법이다. 국내에서 교량의 내하력평가는 계측값과 해석값을 비교하여 산정된 응답보정계수를 사용하여 산정한다. 본 논문에서는 통행차량에 의한 응답보정계수를 결정하는 방법을 개발하였다. 제안된 방법은 차량효과를 고려하기 위하여 컴퓨터 시뮬레이션의 결과에 기반을 두었다. 제안된 방법과 기존 방법의 비교결과는 제안된 방법이 교량의 공용 내하력을 비교적 잘 예측한다는 것을 알 수 있다.
