Ultrahigh-Performance Concrete for Posttensioned Precast Bridge Piers for Seismic Resilience

Precast concrete bridge substructures accelerate construction. Precast concrete piers can also limit residual displacements after earthquakes when used with nonemulative connections. This paper investigates the use of ultrahigh-performance concrete (UHPC) to eliminate damage under moderate to high seismic activity for posttensioned self-centering precast piers. Large-scale laboratory testing was used to assess damage in pier specimens. …
