Elastic behavior of riveted double angle connections in tension Open
T‐stubs and L‐stubs loaded in tension are generally assumed in contact with a rigid foundation. The prying force and stiffness of these components depend on this hypothesis. For double web angle riveted connections, the angle rests on defo…

Stiffness of L‐stubs loaded in compression Open
The stiffness of T‐stubs in compression is generally assumed infinite except for column base plates. For bolted circular flange connections and double web angle connections, the stiffness of L‐stubs and T‐stubs in compression should be det…

Full and partial compression fatigue tests on welded specimens of steel St 52-3. Effects of the stress ratio on the probabilistic fatigue life estimation Open
The fatigue strength of structures subjected to cyclic loading depends strongly on the stress ratio. Particularly, in case of welded steel structures this fact is not considered in the corresponding standards nor in the guidelines. Experim…

Low cost estimation of Wöhler and Goodman–Haigh curves of Ti‐6Al‐4V samples by considering the stress ratio effect Open
The stress ratio effect on the fatigue life of materials is a topic which have been studied by two different approaches. On the one hand, several experiments, performed under different stress ratios are necessary to estimate the correspond…

The emergence of electric arc welding in the construction and reinforcement of railway bridges in France, 1930s–1940s Open
Construction of electric arc welded railway bridges developed in France with the work of Chief Engineer Louis Eugène Cambournac (1886–1973) within the Compagnie des Chemins de fer du Nord from 1935 onwards, then within the SNCF (French Rai…

Statistical modelling of the influence of the stress ratio on the fatigue strength estimation. Application on specimens coming from riveted structures. Open
As testimony of the engineering development during the industrial revolution, old riveted bridges are maintained by several policies worldwide and in some cases because of their historical importance protected. A main concern of these poli…

Contribution to the study of the influence of the stress ratio on the high cycle fatigue behaviour of riveted joints Open
Old riveted railway bridges are part of the cultural and technological heritage in many countries. The assessment of the actual behaviour and the remaining life of these structures is a key economical factor in the management of these brid…

Mean stress effect and fatigue crack closure in material from old bridge erected in the late 19th century Open
The problem considered in this paper is the structural integrity of old materials from the 19th century by means of fatigue crack
\ngrowth problem. The authors present an overview of the fatigue fracture properties of old puddle iron membe…

Understanding the behaviour of wrought-iron riveted assemblies: manufacture and testing in France Open
Numerous wrought-iron bridges can be found in the French railway network. Since most of this architectural heritage was built during the second half of the nineteenth century, these old riveted structures have been in service for over 100 …
