Abstract

Abstract: A systematic study of the tensile properties of all-grade strain hardening cementitious composite (SHCC) from normal strength to high strength was conducted in the present research. The compressive strengths of the cylinder specimens ranged from 43 MPa to 115 MPa. Different combinations of fiber volume fractions and fiber aspect ratios (fiber length/diameter) were employed to investigate the effects of the fiber reinforcement index (the product of fiber volume fraction and fiber aspect ratio) on the tensile properties of SHCC, including mechanical properties and crack patterns. The relationships between the fiber reinforcement index and tensile properties were established at all compressive strengths and compared with the previous experimental values. Moreover, a performance-based design concept was proposed for designing SHCC based on the required mechanical and crack pattern properties, corresponding to the ultimate limit state and serviceability limit state, respectively.
