To enhance concrete toughness and fatigue durability for structural applications, the use of discrete short fibers is effective. Although the use of fiber reinforced concrete (FRC) is continuously increasing in various civil engineering infrastructures, it is still limited with respect to its design codes for FRC structural members. The performance of FRC is related to the post-cracking behavior depending on fiber type, aspect ratio, volume fraction of fiber, and fiber distribution and orientation. The fiber distribution and orientation are affected by boundary conditions of the specimen formwork. The fibers align as 2-D random orientation in a small prism mould, but align as 3-D random orientation in a large size of slab. The aim of this study is to establish the stress-strain constitutive law of the steel fiber reinforced concrete (SFRC) in tension introducing to the non-linear finite element analysis of SFRC slabs. In this study, SFRC prism specimens sawn from square slabs were used under four-point bending tests to determine the mechanical properties such as the flexural strength and the tension softening curve. And, load-carrying capacities of SFRC slabs were compared with the results of 3-D non-linear FE analysis.
