Outline of Final Research Achievements

Experiments of fiber reinforced cementitious composite were conducted at both material and structural scale for a development of robust material for structural material. To improve the shear performance, aggregate and/or steel fiber are added to a conventional PVA/ECC. From the experimental results, it was observed that reduction of the capacity was controlled by adding these materials. The effect was confirmed by the image data analysis and calculation of shear strain obtained from the deformation locally measured. The shear sliding was restricted by the inclusion of aggregate and steel fibers.
