This paper summarizes the results of an ongoing research program examining the blast performance of UHPC columns. As part of the study eight columns built with conventional concrete and UHPC were tested under simulated blast loading using a shock-tube. Parameters considered in this study include effect of concrete type, fiber properties, fiber content, transverse reinforcement, longitudinal reinforcement ratio and strength. The results demonstrate that the use of UHPC results in important performance enhancements in columns subjected to blast loads, including reduced displacements, increased blast resistance and improved damage tolerance.
