A Parametric Study of an old Concrete Trough Bridge using non-linear Finite Element analysis

<p>At least 20% of existing railway bridges in Sweden are reinforced concrete (RC) trough bridge that consist a slab carried by two longitudinal main beams. As these getting old, there is an urging need to assess their remaining capacity with the aim prolonging service lives. The limited literature on topic has pointed out significant difference between predicted available codes and obtained experimentally. In this paper, review Bridge Tunnel Management database (BaTMan) infrastructure Sweden, gain overview current state Swedish bridge, focus bridges. Then, non-linear finite element model calibrated using experimental results previous testing decommissioned bridge. used parametric study where effect key mechanical parameters studied.</p>
