| Abstract: |
Glass fibre reinforced polymer (GFRP) has been applied in underwater concrete floors as part of the permanent structure of two underpasses within a road upgrade project in The Netherlands. This application is unique in view of the permanent nature of the use of GFRP in such structures. These underwater concrete floors are subjected to both downwards loads, such as traffic loads and permanent load, as well as by water pressure uplift. The construction pit consists of permanent sheet piling with a prefab concrete deck on top and a permanent underwater concrete floor between the sheet piling. This permanent underwater concrete floor is reinforced with only GFRP reinforcement. The fibre prevents cracking in the outer zone and increase the tensile strength. |
