In this paper, the results of an experimental study on the effect of fiber volume fraction on the off‐crack‐plane fracture energy in a strain‐hardening engineered cementitious composite (ECC) are presented. Unlike the well‐known quasi‐brittle behavior of fiber reinforced concrete, ECC exhibits quasi‐ductile response by developing a large damage zone prior to fracture localization. In the damage zone, the material is microcracked but continues to strain‐harden locally. The areal dimension of the damage zone has been observed to be on the order of 1000 cm2 in double cantilever beam specimens. The energy absorption of the off‐crack‐plane inelastic deformation process has been measured to be more than 50% of the total fracture energy of up to 34 kJ/m2. This magnitude of fracture energy is the highest ever reported for a fiber cementitious composite.
