摘要：研究了不同掺量的废玻璃粉混凝土在1.5 m和2.0 m落锤高度下的动态力学性能，并提出了一种表征废玻璃粉混凝土动态力学响应的动态损伤本构方程。结果表明：废玻璃粉混凝土的抗压强度随着废玻璃粉掺量的增加而降低；利用MATLAB程序计算得到的分形维数来表征废玻璃粉混凝土的损伤因子是完全可行的；修正后的ZWT非线性率型本构方程的理论曲线与试验曲线吻合较好。 Abstract: The dynamic mechanical properties of waste glass powder concrete with different content under 1.5 m and 2.0 m drop weight height were studied, and a dynamic damage constitutive equation was put forward to characterize the dynamic response of waste glass powder concrete. The results show that the compressive strength of the waste glass powder concrete gradually decreases with the increase of the waste glass powder content. It is completely feasible to use the fractal dimension calculated by MATLAB program to characterize the damage factor of waste glass powder concrete, and the theoretical curve of the modified ZWT nonlinear rate constitutive equation is in good agreement with the experimental curve.

Abstract: The dynamic mechanical properties of waste glass powder concrete with different content under 1.5 m and 2.0 m drop weight height were studied, and a dynamic damage constitutive equation was put forward to characterize the dynamic response of waste glass powder concrete. The results show that the compressive strength of the waste glass powder concrete gradually decreases with the increase of the waste glass powder content. It is completely feasible to use the fractal dimension calculated by MATLAB program to characterize the damage factor of waste glass powder concrete, and the theoretical curve of the modified ZWT nonlinear rate constitutive equation is in good agreement with the experimental curve.
