Fiber-reinforced Ultra-High-Performance Concrete (UHPC) is a cement-based material which combines ultra-high compressive strength and an improved ductility with the well-known advantages of R/C-materials.With these characteristics,the material provides potentially decisive improvements not only for the static structural design of build-ings but also for protective constructions against extraordinary dynamic loadings.Therefore,several experiments were conducted in order to assess the performance of the UHPC for a broad range of strain rates resulting from the different dynamic loadings.Based on the static material properties,dynamic material parameters of the fiber-reinforced UHPC were determined at first under very precise loading conditions using Hopkinson-bar experiments.Building on this elementary testing,the performance of different UHPC structural com-ponents are investigated,analyzed and discussed for the broad range of potential dynamic loading cases.Within this analysis,the UHPC was tested and evaluated against blast and air-craft impact loading scenarios representing the lower half of the potential strain rate spectra.Further additional loading cases like contact-and close-in detonations were also considered,which cover the high strain rates in combination with the examinations of a shaped charge loading.Finally,the suitability of the UHPC is regarded for combined effects taking into account an extraordinary dynamic loading in combination with a subsequent high tempera-ture incident.Within this context,the capabilities for optimizing the material are discussed briefly.
