| Abstract: | A total of 110 specimens have been tested and these specimens were divided into 22 groups according to the different combinations of cement strengths and steel fiber ratios.The main objective of the tests is to determine the relationship between the tensile strength and splitting strength of steel fiber reinforced concrete(SFRC).The stress-strain responses of four types of steel fiber reinforced concrete under uniaxial tension were studied experimentally.In this paper,the mechanisms of reinforcing effect for different types of fibers were analyzed and the stress-strain curves of the specimens were obtained.Based on the test results,empirical equations for the tensile stress and strain relationships as affected by influential parameters are proposed for SFRC.These relationships could be used for references in construction. |
