A research programme in the field of fatigue strength of welded connections of high strength steels (Fe E 460) as well as with regard to the risk of brittle fracture was carried out. Fatigue cracks normally initiate at geometrical discontinuities such as welded details. Therefore the programme is concentrated on welded connections (T-joints and butt welds in 40 and 70 mm plates). The fatigue and fracture behaviour of welded connections in high strength steel under a realistic fatigue loading and at low temperatures was investigated. The research programme includes the following items:

- Material characterization;
- Fatigue and brittle fracture experiments on welded connections (constant amplitude load and random load tests at +20 C and -20 C);
- Fracture mechanics approach to fatigue crack growth.
