“…Since then, extensive research has been conducted to define UHPC with a view to industrialize the technology. [3][4][5][6][7][8][9][10][11][12][13][14] UHPC offers exciting opportunities for new infrastructure, both in urban and suburban regions and in regions where access is limited, particularly where weight becomes important for transportation and cranage. In its current form, UHPC has become commercially available in several countries and across continents, including Europe, Asia, and North America.…”

Breakthrough technology of ultra‐high‐performance concrete (UHPC) introduced in the 1990s exhibits several exceptional mechanical properties that are advantageous in elements of bridge applications. Extensive research has aimed to industrialize UHPC and develop design models. This paper investigates several design models for shear, including a unified approach with that of conventional concrete based on the modified compression field theory (MCFT). An experimental database of UHPC prestressed concrete girders subjected to shear failure is compiled to evaluate model accuracy and a reliability study is conducted to establish appropriate safety factors. The analysis demonstrates that the proposed MCFT‐based model aligns well with experimental results, exhibiting a suitable level of conservatism for design. A reliability assessment of a typical prestressed girder designed according to Canadian Standards Association building and bridge loadings is performed, resulting in a structural reliability evaluation against a target reliability index. The study recommends specific strength reduction and safety factors for design approaches using UHPC.
