Numerical validation of the incremental launching method of a steel bridge through a small-scale experimental study
Chacón Flores, Rolando Antonio; Uribe, N.; Oller Martínez, Sergio Horacio
This article presents an experimental and a numerical study of an incremental
launching process of a steel bridge. The former is deployed in a scale-reduced
laboratory,whereas the latter is performed using the finite elementmethod. The
numerical simulation is based upon realistic transient boundary conditions and
accurately reproduces the elastic response of the steel bridge during launching.
This numerical approach is validated experimentally with the scale-reduced
test performed at the laboratory. The properly validated numerical model
is subsequently systematically employed as a simulation tool of the process.
The proposed simulation protocol might be useful for design and monitoring
purposes of steel bridges to be launched. Results concerning strains, stresses,
and displacements might be inferred from the model and thus compared to
field measurements obtained in situ. The conditions presented at the end of
the article are potentially useful for researchers and practice engineers alike.
