    Abstract:

    Due to the unique geometry of hooked end steel fiber(HSF),frictional pullout energy of HSF and plastic deformation energy of steel fiber hooked end during fiber pullout process were theoretically derived,respectively.Then,energy superposition principle was adopted to calculate the total energy consumption during HSF pullout process.Good performances that were obtained in comparison with experimental results of single HSF pullout test well support the validity and accuracy of this proposed model,which indicate applicability of this model to a further prediction of fracture energy of hooked end steel fiber reinforced cementitious composites (HSFRCC).
