Reliability-Based Assessment of UHPC–Normal Concrete Interface Shear in Bridges: Comparison of AASHTO Shear Friction, Deterministic, and Probabilistic Machine Learning Models
Reliable shear transfer across the ultrahigh-performance concrete (UHPC)–normal concrete (NC) interface is critical for composite action in bridge rehabilitation and accelerated construction, including overlays, joints, and closure pours. This study develops a reliability-based comparative framework for UHPC-NC inter...
