摘要

Provisions for the fatigue safety evaluation of existing bridges rely on a narrow knowledge basis. The fatigue safety of existing reinforced concrete deck slabs often cannot be verified if current fatigue design provisions are applied. A brief discussion of fatigue models allows for the determination of their utility in a stepwise approach to fatigue examination of existing bridges. To enhance the knowledge for more realistic predictions of the remaining fatigue life of existing structures, results of an ongoing research with fatigue tests on slab-like concrete beams are presented and interpreted. First results indicate that current fatigue design pro- visions appear to be conservative and that the fatigue reliability of existing deck slabs is satisfactory if the principles of good fatigue design and construction practice have been respected.
