Abstract
■ This paper proposes flexural design recommendations for precast, pretensioned ultra-high-performance concrete members, including experimental verification and numerical examples. The experimental program includes three examples: a precast, prestressed concrete decked I-beam; a precast, prestressed concrete floor slab; and a precast, prestressed concrete bridge box beam. A comprehensive design example of a 250 ft (76.2 m) long decked I-beam is presented. A design spreadsheet is available online to aid designers in implementing the proposed recommendations.
