Abstract

In this paper, method of single plane shear test under tensile stress as normal stress on crack surface is conducted to clarify shear transfer mechanism on crack surface of ECC (Engineered Cementitious Composites). The PVA fiber is adopted for ECC. From the test results, shear strength on crack surface is about half of tensile strength. This means that normal stress for crack surface is possible to keep crack strength under shear. Predicting method for shear capacity of steel reinforced ECC beams is proposed based on the arch-truss method with the summation of the tensile strength of ECC which is obtained by bending test. The experimental values show good agreement with calculated values.
