RESIDUAL FATIGUE LIFE OF OLD RAILWAY BRIDGES

This paper deals with experimental investigations to determine the residual service life of five complete German Federal Railway bridge structures and on their components, and three bridges from the suburban railways of Berlin. The results of these component tests are compared with data known from literature as well as with other results of similar investigations performed at the institute in Karlsruhe. The 5 bridges dated from 1877-1899, and had lengths of 4.50, 4.80, 6.80 and 9.5 metres; the 4 main girders of the Berlin suburban bridges dated from 1899-1913 and were 5.0, 8.5 and 18.5 metres long. The purpose of the fatigue tests was to discover facts about rivet slip, rivet initial load, displacement under shear stress and load distribution on various elements of a structural member. The investigations are continuing. For the covering abstract see IRRD 864118.
