Orthogonal Test and Mesoscopic Numerical Simulation of Dynamic Compression Performance of Ultra-High Performance Concrete at Elevated Temperatures
To evaluate the influence of fiber content, temperature, and loading rate on the dynamic compression performance of ultra-high performance concrete (UHPC), orthogonal Split Hopkinson Pressure Bar (SHPB) tests were performed on 120 MPa UHPC specimens. Range analysis of the test data reveals that the steel fiber content...
