In this study, the two BFR wagons with PSC sleepers (as previously detailed) are placed on the bridge with loads coinciding with the axle position as in the field test. These loads are directly applied at the top of the bridge, which then gets transferred to the arch through the fill. The vertical deflection obtained at the crown of Span 1 is 0.55 mm (versus a measured value of 0.57 mm for BFR with 200 sleepers). The corresponding values of computed and measured vertical deflection at the crown of Span 2 are 0.54 and 0.6 mm, respectively. This indicates that the material properties of modulus of elasticity and Poisson’s ratio used for the masonry and the infill in the analysis are reasonable, leading to computed deformation being in agreement with the deformations observed at field and thereby calibrating the material model.
