Pombo, (Editor), "Proceedings of the Third International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 144, 2016. doi:10.4203/ccp.110.144

Keywords: FE-DE, finite element, discrete element, masonry arch bridges, arch-fill interaction, collapse mechanism, pushover analysis, load carrying capacity.

Summary

In this paper, the feasibility of the utilization of a combined finite element/discrete element (FE/DE) approach to investigate the behavior of masonry arch bridges is proposed. Attention is paid to the assessment of the load carrying capacity by means of a suitable coupled FE/DE two-dimensional approach. This paper outlines the fields and limits of applicability of the FE/DE method to the study of masonry arch bridges. The main contribution is to evaluate the applicability of FE/DE, in particular its reliability to describe the nonlinear behavior of masonry arch bridges under increasing static loads, to catch kinematic failure mechanisms and collapse load multipliers, as well as to evaluate the role played by the backfill.

A discussion on a possible approach to FE/DE modelling of the Venice trans-Lagoon masonry arch bridge is proposed. With such a purpose, a series of parametric analyses has been conducted in order to evaluate the influence of the different parameters involved on the behavior of the bridges. Pushover analyses have been performed to investigate the nonlinear behavior up to the collapse and up to a clear formation of a failure mechanism in the model.
