4. General rules for SRI analysis using finite element models
The effects of track/structure interaction must be evaluated in terms of longitudinal actions transiting through the fixed supports, additional stresses in the rail, and absolute and relative displacements of the rails and deck, with a view to comparing them with the regulatory values set by standard EN 1991-2.
Section 1.7.3 of UIC standard 774-3R gives recommendations for establishing an IRS finite element model, as does EN 1991-2. This article will present the most important
4.1 Rules for model development
Figure 25 shows the overall typology of models to be developed for SRI calculations....
