Precisely, researches have been done on Fiber Reinforcement Self-Compacting Concrete (FRSCC) which can divide into two different fields, material serviceability and mechanical rheology investigations. The mechanical aspect of FRSCC has been investigated to provide the constitutive models of shear and flexure capacity, tensile or compressive zone data. The characteristics of FRC are determined by post-cracking behavior and FRSCC is controlled by SCC workability. By using FRSCC the costs and construction period reduce significantly and its ability to place irregular section in terms of congestion of stirrups and bars and thin section is another great aspect. Consequently of this capability is to arrest cracks, fibers mixtures increased tensile strength, both at ultimate and at first crack, especially under flexural loading. The other ability of fibers are to hold matrix after extensive cracking. The transition failure from brittle to ductile by fibers is another ability of fibers which can absorb energy and survive under impact loading. In this study, investigate the fibers influence by two techniques, direct and inverse technique.
