Shear behavior of UHPC beams
Investigating shear transfer and the combined contribution of fibers and stirrups in ultra-high-performance concrete beams.
Engineering question
How do shear-span ratio, fibers, and stirrups influence the mechanisms that govern UHPC beam behavior?
- Research context
- McGill University
- Period
- Postdoctoral research
- Research collaborators
- Z. Quan and Yi Shao
My contribution
- Investigating transitions between beam action and arch action in UHPC beams without stirrups.
- Combining structural experiments with analytical predictions of shear response.
- Examining fiber and stirrup configurations to improve material use and shear performance.
Findings and relevance
The studies clarify changes in shear-transfer mechanisms and explore reinforcement configurations for UHPC beams. The work on failure-mechanism transition received a 2026 Featured Paper Award from Engineering Structures.
Continuing questions
Future interests include combining UHPC and FRP reinforcement in durable structural elements.
