Assessment of the Forsmo Bridge Case Study Steel truss arch railway bridge requiring upgrading for increased axle loading Iterative model development to incorporate strain gauge results Global and local modelling to assess Ultimate, Servicibility and Fatigue Limit States The use of on-site measurements to re?ne and improve an initial ?nite element model of a structure for subsequent detailed analytical investigations is invaluable. Ramboll successfully used strain gauge measurements on the Forsmo Bridge in Sweden to ?ne-tune a LUSAS Bridge model prior to carrying-out an in-depth assessment of the structure for a proposed increase in freight train axle loading.Overview Built in 1912, the Forsmo Bridge is a 263m long, 50m high riveted steel-truss-arch railway bridge which crosses the Aangerm
