Numerical analysis of the Vattedal bridge strengthened with UHPC overlays
Abstract
This master thesis addresses how ultra-high performance concrete strengthening can affect the structural response of a single-span concrete bridge in Vattedal, Tysnes.
Several FE-models with different UHPC configurations are analyzed in Abaqus and compared to the reference bridge. Model updating was carried out by performing operational modal analysis on the obtained data from frequency measurements.
The presented results compare the different UHPC configurations in terms of force-displacement curves and crack development.
