Response of Concrete-Filled Tubular FRP Arches to Construction-Induced Loading

摘要

In this study, the structural response of concrete-filled tubular FRP arch bridges to construction loads, including filling of the arch with wet concrete and backfilling the structure after the arch concrete is sufficiently cured, is assessed. Local tube buckling capacity was examined experimentally and using FEA. The effect of soil backfilling was addressed with a nonlinear beam FE model that tracks the installation of each soil lift on alternate ends of the structure.
