- Synopsis:
- As the Ultra High Strength Fiber Reinforced Concrete (UFC) does not need to be reinforced by bars, thin plates can be produced and applied for the concrete structures. The UFC plates can effectively extend the applications to the shell structures as well as the panel members and the lining members for tunnel. In this study, the flexure and shear loading experiments have been carried out under the various support conditions to clarify the load-bearing capacity and the fracture behavior of the UFC thin plates. The load bearing mechanism of the UFC plates was examined through various simple calculations and the non-linear FEM considering the tension softening behavior. The behavior and applicability of UFC pre-cast panels joined by different methods were also compared experimentally.
