Calculation of bridge deformations due to train passages by the use of strain and acceleration measurements from bridge monitoring supported by experimental tests KU Leuven
A monitoring campaign has been performed on a filler beam railway bridge for high-speed trains, measuring strains and accelerations due to train passages. For this purpose a very dense grid of measurement sensors was applied to the bottom side of the bridge deck, which allows the calculation of bridge deformations from strain measurements. Within this calculation the location of the cross section's neutral axis plays an important role, since it ...
