| Abstract: |
This work analyses the collapse of two Bailey-type modular bridges in Costa Rica, one the Balsa- Santa Clara River bridge in 2018, and the other the Cataratas River bridge in 2015. Both bridges had the same main characteristics and were installed as temporary structures but remained in place until the day of the collapse. The analysis demonstrated that the Cataratas River bridge failed because the compression strength of the top chord was exceeded by a load 2.3 times greater than that of the Balsa River bridge. The Balsa River bridge failed due to a loss of structural stability caused by the absence or failure, prior to collapse, of the connection between at least one transverse beam |
