Abstract
This research, carried out with the financial help of the ECCS, concerned the fatigue strength of orthotropic steel decks of road bridges. It followed two phases that were concerned with the collection of traffic data and measurement of stresses produced in bridges. Fatigue tests under constant and variable amplitude were carried out on stiffener-plate connections, stiffener-stiffener connections with U and V shapes, and stiffener cross-beam connections. From the tests results and calculations some conclusions can be drawn which are directly usable in bridge design. However, some unexpected behaviour occured and some connections need more investigation.
