Research Abstract

Highway bridge are subjected to heavy truck traffics, which causes some fatigue problem to the secondary member of the bridges. Both the member and the weight of the trucks increased , especially during and after the rapid economic growth in Japan in 1960's and 1970's. The highway bridges were traditional not designed for fatigue because the truck loading caused relatively small stress range to the members, compared with the railroad bridges. However, the fatigue cracking were observed recently in many highway bridges, and assessment for fatigue seems necessary.
Service stress measurement were carried out on several highway bridges by histogram recorder, and fatigue damages were computed using the Miner's cumulative damage rule. The result revealed that the service stress ranges in main members of the highway bridges were relatively small and a very little chances seemed to exist. However, the service stress ranges in several details which experienced fatigue crackings showed rather high stress ranges, and hence short remaining fatigue lives.
