Outline of Final Research Achievements

Shear capacity of various Fiber Reinforced Cementitious Composite (FRCC) beam was experimentally investigated considering shear stress transfer characteristics along the crack surface. Numerical evaluation was also conducted by Finite Element Method (FEM), in which shear stress transfer model of FRCC, developed in this study, was introduced to evaluate the effect of fiber bridging at the crack. As the results of direct shear loading tests, the fiber bridging did not have much effect on the shear stress transfer along crack surface of FRCC but the fracture energy which was dissipated energy during crack opening had effects on. This result was also confirmed by FEM analysis considering shear bridging in the constitutive model. Therefore, it is important to evaluate properly the tension softening behavior as well as to consider the shear stress transfer along the crack surface in order to estimate the shear capacity of FRCC.
