Riveted railway bridges with already long structural lives can still be commonly found in service in Europe. In light of their peculiarities, they are often prone to fatigue damage; nevertheless, very few prescriptions regarding fatigue assessment of these structures can be found in current European provisions. Within this framework, the present pa...

... of local-scale FE analyses on LC and TD connections are summarized in Figure 6a,b and Table 3, in terms of (i) von Mises stress distributions associated with the highest equivalent stress range ∆σ eq,max and (ii) ASED calculations for each equivalent stress range value ∆σ eq,i . Relevant mesh sensitivity analyses (average mesh size s = 1-5 mm) for such quantities are also reported. ...Context 2
... this end, the substantial mesh-insensitivity of the ASED range can be observed in Figure 6a,b, in compliance with remarks from [35,36]. Table 3 also shows how significantly higher values of ∆W were attained in the LC connection compared with the TD. This outcome plausibly resulted from (i) the presence of larger mean stresses, (ii) the influence of secondary bending due to the moderate degree of flexural restraint provided by the riveted backing plates, and (iii) the larger reduction of net cross-rection due to rivet holes. ...Citations
A 120-year-old railway truss bridge over the Bóbr River, Poland is investigated in this paper, from the mechanical and chemical properties of the materials-by testing of old steel samples in a lab-through geodetic measurements, bathymetric measurements of the riverbed and dynamic measurements of bridge spans under service load-to the analysis of structural behaviour-by finite-element modelling. The mechanical and chemical properties of the structural old steel are investigated by testing steel elements extracted from the old bridge. Structural analysis shows that the bridge is eligible for renovation or replacement for a new one due to unfulfilled today's load requirements in terms of bearing capacity. The paper begins with a survey of chosen literature carried out on the investigation of the old steel railway bridge's subject matter. This paper can provide scientists, engineers, and designers with an experimental and structural basis in the field of old steel riveted railway truss bridges.
