Dynamic increase factors for high-performance concrete in compression using split Hopkinson pressure bar

This paper provides dynamic increase factors (DIF) in compression for two different High Performance Concretes (HPC), 100 MPa and 160 MPa, respectively. In the experimental investigation 2 different Split Hopkinson Pressure Bars are used in order to test over a wide range of strain rates, 100 sec1 to 700 sec—1. The results are compared with the CEB Model Code and the Spilt Hopkinson Pressure Bar technique is briefly described.
