In the framework of a research project concerning the brittle fracture resistance of “old” civil steel structures, mechanical and fracture mechanics parameters are determined on specimens from such structural steels. The specimens were sampled from steel structures erected between the years 1904 and 1930. The main focus was on fracture toughness testing according to the Master Curve (MC) approach according to the test standard ASTM E1921. Except one steel all fracture toughness values followed the Master Curve description and gave valid T0 values. The dataset was characterised as inhomogeneous and the MC based evaluation approaches of the SINTAP procedure characterising the brittle fraction of a dataset had to be applied.
