Structural analysis of a stone arch bridge under incremental railway static loading
This paper reports on the modelling strategies used to represent the structural behaviour of a masonry single-arch railway bridge. The bridge structural behaviour is simulated by a 3D finite element model, in which the different bridge components are represented by homogeneous materials. The material nonlinear behaviour is simulated using a Drucker-Prager model. The assigned material properties are based on material testing, performed in similar stone masonry structures. The load-carrying capacity is evaluated using a 3D Ansys model and with a RING model of the bridge under incremental static loading representing normal railway traffic with appropriate configurations on the bridge deck, and the results compared. ; Part of this work reports to research financially supported by Project POCI-01-0145-FEDER-007457—CONSTRUCT, Institute of R&D in Structures and Construction, funded by FEDER funds through COMPETE2020 and by national funds through Fundação para a Ciência e a Tecnologia (FCT). It also includes research supported by the FCT project PTDC/ECM-EST_1691/2012 – Experimental and Numerical Characterization of Structural Behaviour of Stone Masonry Arch Bridges under Railway Traffic Loading, Application to Existing Portuguese Bridges and by FCT PhD programme PD/BD/127812/2016 (iRail).
