Precast Bridge Parapets in Ultra High Performance Fiber‐Reinforced Concrete
New designs of precast bridge parapets adapted to utilization of ultra high performance fiber‐reinforced concretes (UHPFRC) have been developed by using non linear finite elements calculations. The mechanical behavior of each design was established for a quasi‐static loading and a dynamic loading equivalent to a vehicle impact. Results of quasi‐static tests have shown that precast UHPFRC parapets reached a capacity and a ductility equivalent to the reference parapet. Dynamic tests have demonstrated that the residual resistance of UHPFRC parapets after a series of impacts corresponds to their original capacity. Finally, the global efficiency of each parapet design was evaluated. The mechanical performance was considered with regards to the fabrication costs and the construction time required for their installation on a typical bridge. The analysis permitted identification of designs with the best commercialized interests.
