Synthesis Study Quantifying the Effect of UHPC Fiber Dispersion and Orientation in Structural Members

Ultra-high performance concrete (UHPC) design codes from other countries include reduction factors based on UHPC placement and fiber orientation for full-scale specimens. This research is a synthesis study to understand those factors and what research studies or rationale they are based upon. This research will also document the work which has been done thus far to understand the effect fiber orientation has on the mechanical properties of UHPC at a material level.
