Abstract

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 paper illustrates the advanced fatigue assessment of an Italian riveted railway bridge selected as a case study. For this purpose, multi-scale finite element modelling of the bridge was developed, and the most critical details were assessed through application of the advanced strain energy density (SED) method. The obtained outcomes were compared both with other studies in the literature and prescriptions from the current and upcoming versions of EN1993-1-9.

现有砌体桥墩上铆接铁路桥梁的高级疲劳评估：意大利案例研究

在欧洲，结构寿命已经很长的铆接铁路桥梁仍在使用中。鉴于其特殊性，它们往往容易发生疲劳破坏；然而，在欧洲现行规定中，有关这些结构疲劳评估的规定却寥寥无几。在此框架内，本文以意大利的一座铆接铁路桥为例，对其进行了先进的疲劳评估。为此，对该桥进行了多尺度有限元建模，并通过应用先进的应变能量密度 (SED) 方法对最关键的细节进行了评估。所获得的结果与其他文献中的研究结果以及 EN1993-1-9 当前版本和即将推出的版本中的规定进行了比较。
