The potential of UHPFRC strengthening on real structures is still unknown. In this study, the damaged structural elements would be repaired and reinforced using UHPFRC to assess its effectiveness in a realistic context.
This project will provide a validated assessment methodology for the residual capacity of individual components and the complete bridge deck, as well as a strengthening technique with extended durability.
More information about the project
Objectives
Determine the level of corrosion on intermediate slabs
Estimate the residual capacity of the slabs theoretically and experimentally
Evaluate the flexural and shear reinforcement obtained from the repaired slabs using UHPFRC without extra thickness
Provide a complete procedure for the evaluation of residual capacity and for the reinforcement of structures damaged by corrosion
Validate the equations in the Swiss standard for concrete sections repaired with UHPFRC
Duration
3 years (the project started on March, 2020)
Bridge elements
Location: approach span (reinforced concrete structure) near Île des Soeurs
