Study on Damage Constitutive Model of Reactive Powder Concrete in Uniaxial Tension
In this paper, the damage constitutive model of reactive powder concrete (RPC) in uniaxial tension is investigated. The relationship between the uniaxial tensile strength of RPC and the steel fiber admixture was analyzed by preparing RPC specimens with different steel fiber volume admixtures for uniaxial tensile tests, and the stress–strain curves were recorded. The test results show that the uniaxial tensile strength of RPC is significantly enhanced with an increase in steel fiber doping, especially after the doping amount is greater than 2%, showing a linear increase. Based on the classical damage mechanics and Weibull distribution, the damage evolution equation and the constitutive model of RPC uniaxial tension were established. The validation shows that the model can effectively describe the damage process of RPC in uniaxial tension, which provides a theoretical basis for the application of RPC in engineering practice.
