Ultra-High Performance Fibre-Reinforced Concrete (UHPFRC) is an innovative concrete type with a high compressive strength and a far more durable character compared to conventional concrete. UHPFRC can be applied in structures with aesthetic appearance and high material efficiency. Shell structures are spatially curved surface structures of which the exceptional behaviour can be referred to as 'form-resistant structures' which resist loads by developing stresses in its own plane. This paper describes the optimization process for the application of prefabricated rib-stiffened UHPFRC-elements. A spherical shell is designed with a span of 150 m and a height of 37.5 m. The designed prefabricated elements have a weighted mean thickness of 44 mm and a 'thickness over radius'-ratio of 2130, which is about 20 times more slender than an egg shell. The study shows that a large span shell structure produced with UHPFRC-elements is a promising concept.
