Abstract:The experiment methods of the bonding strength between deformed steel fiber and concrete was self-designed.24 groups of specimen with the parameter of the concrete matrix strength,the shape and the embedding angle of the steel fiber were made. The test results indicate that the concrete matrix strength,the shape and the embedding angle of the steel fiber are the main factors for the bonding strength and the dissipated energy during the fiber pulling out.The bonding strength increases following with the increase of the concrete matrix strength.The bonding strength and the dissipated energy performances of B (staple shape)steel fiber are better than those of the J(shear straight line shape)steel fiber.The bonding strength and the total dissipated energy increase following with the increase of the embedding angle.
