High performance fiber reinforced cementitious composites (HPFRCC) have, tensile capacity of several percent strain. The objective of this study is mainly to evaluate uni-axial tensile model of HPFRCC for design procedure utilization and certification on construction site. In this paper, experimental evaluation method for first crack strength and strain is proposed using results of splitting and compression test of cylinder test pieces. The first crack strength obtained by splitting test shows a good agreement with that obtained by uni-axial tensile test using hourglass test piece. Elastic modulus obtained by compression test has a good relationship with that of uni-axial tensile test. As a result, crack strength and strain can be evaluated by the simple experimental tests.
