A system-based model for fatigue assessment of riveted railway bridge connections, comprising a number of basic components, is presented in this paper. Probabilistic fatigue load spectra are developed through Monte Carlo simulation of train passages over a finite element model of a typical, short-span bridge. Uncertainties arising from loading, resistance and modelling sources are taken into ac...

Steel structures built between 1850 and 1940 are mostly made of mild steel. Riveting was the dominating joining technique. Fatigue failure respectively fatigue safety is major concern if these cyclic loaded such as bridges hydraulic steel structures. Considering period operation almost hundred years, determination remaining life main aim assessment The clamping force rivets significantly influe...

Combining dissimilar parts has become imperative for developing the structures based on lightweight materials, such as metal alloys, polymers or polymer matrix composites, and this one of solutions to reverse current trend CO2 emissions in transport sector. However, given usual property disparities, joining materials multi-material multi-purpose raises new engineering challenges. Advanced proce...

Nowadays, the Riv(et)-Bonding technique has become a major joining approach in automotive industry. It effectively incorporates benefits of adhesive bonding and self-pierce riveting (SPR), but overcomes their individual drawbacks. Finite element (FE) simulation SPR process now plays very important role during product design manufacture processes field. However, there is no reported progress Riv...

Recent studies have found that stringer-to-cross-girder connections in riveted railway bridges are susceptible to fatigue cracking. Fatigue damage in these connections is caused by secondary, deformation induced effects. These effects are difficult to interpret in terms of a single, applied stress descriptor, which is customarily used in an S-N assessment. In order to address this problem, and,...

In an innovative vision of manufacturing, orbital riveting is a joining technique characterized by high efficiency, energy saving, low costs and noise. It cold forming process where tool rotates at fixed angle (i.e., typically 3° to 6°) create sweeping line pressure around rivet. This movement progressively promotes, with each rotation, the collapse rivet shank down onto upper substrate joint, ...

In this paper, three-dimensional modeling of the fatigue crack growth profiles was performed in a simple riveted lap joint. Simulation results showed that mode I was dominated on the one side of the plates and the crack straightly grew on this side, while the other side of the plates was in a mixed-mode condition and the crack propagation path was not straight on this side. Afterward, the fract...

Abstract Lightweight design in the form of intelligent multi-material structures that combine advantages high strength steel and continuous fibre reinforced thermoplastics (CFRTs) gain increasing relevance. In this context, joining operation is a major challenge as it has to be time cost efficient resulting joint exhibit mechanical durability. One possible approach use cold formed pin structure...

This study aimed to experimentally analyse the robustness of riveted steel bridges based on truss-type structures and define practical recommendations for early detection local failures before they cause progressive structural collapse. Although there are many experimental studies collapse buildings, those either theoretical or deal with actual collapses. paper describes a unique case 21 m full...

Although many riveted bridge structures made of old structural steel from the 19th and early 20th centuries are still in use today, there is usually no need to replace them. When assessing these with regard necessary refurbishment or strengthening measures, engineers information about remaining fatigue lifetime particular. Often sufficient life can be determined based on normative S-N-curve ass...
