Abstract
High Performance Fiber Reinforced Cementitious Composites (HPFRCC) shows superior tensile ductility, however its shear resistance property at crack surface shows lower performance. It was found to solve this problem that coarse aggregate improves load-carrying resistance for shear. Also, when this material is used as structural element, it is essential to evaluate both wide range of strain distribution and local scale crack behavior appropriately. In this research,image data analysis was adopted to investigate into these two features at the same time in shear beam tests. Through beam tests, the efficiency of course aggregate in terms of contribution for shear performance was observed. Also, problems of image data analysis are pointed out.
