00925njm 22002777a 4500 dc García Gómez, Felipe author Martínez Martínez, José Antonio author García Castillo, Luis Mª author 2022 This paper presents an investigation on how to model a backfill masonry arch bridge using the discrete element method (DEM). The PFC2D software is used for this purpose. A certain backfill masonry arch bridge is modelled, with different types of fill, mortar and voussoir materials. A biaxial test has been programmed using ‘FISH’ code to obtain the micro-parameters used in the model so that they match the macro-parameters obtained from a real biaxial test. The arch is loaded until its collapse in three different load cases. Further discussion on the influence of the backfill parameters is presented as well as a sensitivity analysis for the arch bridge. 1748-6025 http://hdl.handle.net/10259/8676 10.1080/17486025.2019.1680883 1748-6033 Discrete element mehtod Backfill masonry bridge PFC2D Geomechanical modelling Soil-structure interaction Influence of the backfill parameters in distinct element modelling of a backfill masonry arch bridge through the PFC2D software
