Abstract
This paper presents the results of numerical studies on the responses of normal-strength concrete (NSC) and ultra-high performance concrete (UHPC) beams subjected to impact loads using an advanced single-degree-of-freedom (SDOF) model. The constitutive models and material parameters were developed and calibrated based on the results of static and dynamic testing on NSC and UHPC cylinders at the Center for Infrastructure Protection and Physical Security (CIPPS), University of Florida. The results from the SDOF models were compared to the results obtained by static and impact testing of full-scale NSC and UHPC beams. The numerical models provided good correlation with the impact test results and were able to predict the peak response quantities with reasonable accuracy.
