DIRECT TENSILE DAMAGE MODEL OF ULTRA HIGH PERFORMANCE CONCRETE

摘要：

　　Direct uniaxial tension test of ultra high performance cemtitious compisites I shape specimens have been investigated in this paper.A nonlinear analytical model based on continuum damage mechanics is developed to characterize tensile stress-strain constitutive response of UHPC.Basic governing equations of damage evolution and material constitutive relation are established considering random damage which conforms to Weibull type distribution.Calculation suggests that Weibull distribution can describe damage evolution of UHPC and used to predict the constitutive relation and damage evolution equation.
