| Outline of Final Research Achievements |
The bridging law of High-Performance Fiber-Reinforced Cementitious Composite (HPFRCC), in which short discrete fibers are mixed into cementitious matrix, can be determined by the balances of fiber orientation, snubbing effect, and fiber strength degradation due to orientation angle to crack surface. The bridging force increases by the rearrangement of fiber orientation produced by a vibration rod or device like comb. This increment causes the large effectiveness for improvement of structural performance of beams and beam-column joints. The structural performance of HPFRCC members can be evaluated by the models of bridging law that is characterized by the orientation intensity in the orientation distribution function.
