Summary

Curved guard fences have been used along curved road sections and bridges to protect vehicles and their occupants. The current Japanese specifications are not concerned about the curved guard fence in the design and researchers have suspected that in the same collision conditions that curved guard fences are more dangerous than straight ones. On the other hand, this study found that the impact angle between vehicles and guard fences in some cases of curved road sections and bridges is larger than the angle allowed for in the Japanese specifications. Since 2004, two requirements of a landscape-friendly appearance and a flow in the road user's view from bridges were required for guard fences in Japan. Those improvements have required a smaller and slender form for the guard fence. Thus, the objective of the research, reported in this paper, is to develop a new-type of curved steel bridge guard fence satisfying the improved functions. Then the performance of this curved guard fence under the larger impact angles is investigated.
