N2 - Based on different direct tensile test methods of concrete in the present studies, the effects of specimen shape and grip method on the stress distribution in specimen were discussed and a series of tests were carried out by using epoxy adhesive method. Influences of fiber content and fiber type on tensile strength, tensile strain and residual strength of concrete have been studied. The specimen dimension was 100mm×100mm×200mm and the content of Macro-PP fiber was 6 kg/m3, 7 kg/m3, 8 kg/m3, 9 kg/m3 and 10 kg/m3, respectively. The content of steel fiber used in the contrast test was 30 kg/m3 and 40 kg/m3. The test results indicate that Macro-PP fiber can enhance the tensile strength and tensile strain at peak load effectively. Compared with plain concrete, it was found that the tensile strength and tensile strain at peak load of concrete with 9 kg/m3 macro-PP fiber increased by 43 % and 41% respectively.
