The assessment of the total service life of steel constructions shall gain importance in the near future due to the increasing significance of building preservation and building modernization. The main cause for failure of existing structural steel constructions under cyclic loading effects is material fatigue. Most steel constructions are however failure tolerant. For economic reasons, this behavior can be considered by including the crack propagation phase into the assessment. In this
