“…Section 6 outlines the final adoption of the implemented algorithm to evaluate the dynamic response of a 1D multispan FEM model of the upper continuous beam of a historical railway riveted iron arch bridge, namely the Paderno d'Adda Bridge (1889), which has recently been made the target of a wide research project concerning the determination of its present structural capacity (see Ferrari et al [44][45][46]), in both static and dynamic mechanical contexts. The technique originally considered by designer engineer Jules Röthlisberger to conceive and calculate the bridge is briefly introduced and some technical aspects are summarized, to provide an introductory view about the architecture and structural functioning of such a monumental railway bridge.…”

The present work outlines an original numerical modelization approach for Moving Load (ML) beam problems, by a dedicated object-oriented C++ parallel computing FEM implementation, with the purposes of performing efficient numerical analyses resolving the complete dynamic response of beams under the effect of a high-velocity ML. Alongside, main framing state-of-the-art reviews are attempted, on the principal involved issues of: ML context and physical description, numerical FEM modelization, parallel computing implementation. Running ML example cases are explored, for a (long) finite beam on a (visco)elastic foundation and for a continuous beam of a historic railway iron bridge, with per se interesting engineering outcomes. The contribution may serve as a guideline paradigm to readers that may be novel to the treated topics, though motivated in adventuring in the computational challenges involved in the present mechanical research context.

“…The arch form has facilitated the passage of wide openings and is therefore the most preferred form. In today's societies, cultural and socio-economic differences add originality and aesthetics to arch bridges [8][9][10]. However, due to its geometrical design, it is exposed to pressure.…”

Historical structures are cultural heritage constituents that convey the traces and characteristic features of civilizations to the present days. One of these structures, which are among the monumental artefacts, are historical bridges. To protect historical buildings, 3D photogrammetric documentation of these structures, detailed determination of geometric and material properties and performing computer-aided structural analysis using appropriate modelling techniques are very important. The aim of this study is to present an effective, reliable, and fast multidisciplinary approach for the analysis of historical masonry bridges. The aforementioned approach is presented as an example for the behavior of the recently restored historical Ayvalıkemer (Sillyon) masonry arch bridge under possible loadings. Terrestrial laser scanning (TLS) was used to determine the bridge geometry with high accuracy. The point cloud data obtained from TLS was simplified and a three-dimensional CAD based solid model of the structure was created. This solid body has been formed the basis of the macro model for structural analysis. CDP material model was used to describe the inelastic behavior of homogenized structure. Thus, an analysis was carried out which presents the structural behavior of a historical bridge with high accuracy and reliability.

This is the accepted version of the paper.This version of the publication may differ from the final published version. This is. However, the collapse mechanism of this type of structure is not well studied. In this paper, loading is performed and the responses of the structure is investigatedand a three-stages collapse 14 mechanism of this type of structure was observed. Permanent repository link15
