Abstract: Upon request of the Region Nord-Pas-de-Calais, the architect Philippe PROST designed an International Memorial to pay tribute to the 580.000 soldiers, regardless of nationality, who perished during World War I. The architect chose Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) to build the Memorial; the entire structure is made of precast voussoirs, and part of it is prestressed by post-tension. Eiffage TP was awarded the contract and built this extraordinary civil engineering work with BSI®, Eiffage’s own UHFRPC. This material’s extreme durability will allow it to remain through the upcoming century a part of the necropolis on the hill of Notre Dame de Lorette. The International Memorial is one of the first works in UHFRPC designed according to AFGC UHPFRC 2013 Recommendations. Material shear strength properties were fully used to prove the resistance of precast UHPFRC segments in the curved prestressed structure. The main difficulty for structural studies was to justify the beam under the effect of the torsion generated by its very large curvature. Unlike habits, preload has been designed to maximize the shear strength of the structure. This architectural prowess was a challenge for both detailed design and on-site construction.
