【 摘 要 】

Test method by direct stretching. The failure modes and failure mechanisms of concrete specimens with 0%, 10% and 20% of waste glass powder at five different loading rates were studied. The uniaxial tensile view of waste glass powder concrete was established by using parallel-bar model PBS. The damage model is the modified parallel model, and the damage relationship is very similar to the stress-strain curve in the test. It shows that the concrete uniaxial tension meso-damage model can be used in this test. The ultimate tensile strength of waste glass powder concrete increases with the increase of loading rate. The relationship between dynamic tensile strength and loading rate is studied. The linear regression fit is applied to the influence of loading rate and dynamic tensile strength to obtain dynamic tensile strength. The increment is approximately related to the loading rate.
