Abstract: Uniaxial tensile test of ultra-high performance concrete (UHPC) is a basic material test to analyze its tensile properties and tensile constitutive relationship. Through optimization of the shape and size of the specimens, the success rate of the test has been greatly improved. Howe-ver, due to the difference in the connection device and reinforcement method, the success rate of each institution is uneven. In order to further ensure the success rate of the uniaxial tensile test, the influence of four common connection devices and three reinforcement methods on the success rate of the test were systematically analyzed through experimental research and numerical simulation, and the optimal test scheme was selected. The results showed that the in-plane clamping device has the advantages of reliable connection and simple operation, which is suitable for popularization. However, there is a problem that the size processing error or micro deformation of the clamp leads to the narrowing of the contact surface with the specimen, intensifies the stress concentration caused by clamping, and makes it impossible to control the main crack to be located in the measuring range; both flexible reinforcement (paste carbon fiber reinforced polymer) and rigid reinforcement (paste aluminum sheet) of the contact area between the specimen and the fixture can effectively solve the above problems, increase the success rate. In addition, the influence of the aspect ratio and volume fraction of steel fibers on the damage constitutive relationship of UHPC under uniaxial tension was investigated by using the optimal uniaxial tensile test method. The damage evolution law of UHPC under uniaxial tensile load was explored through acoustic emission (AE) monitoring. The damage factor was constructed using AE parameters (cumulative counts ratio), and the uniaxial tensile da-mage constitutive relationship of UHPC considering the influence of steel fiber was obtained.
