30/1/2015 · Dynamic tests were conducted on four TCC beams with a clear span of 5.8 m to assess their dynamic performance by evaluating their modal parameters. The Fundamental frequency of the beams was also predicted using five analytical methods and the …
The dynamic mechanical properties of HPESA concrete materials were correlated with impact-loading strain rates. At different strain rates, three types of stress–strain curves were exhibited: single-peak, double-peak, and transition types.
As the loading strain rate increases, the uniaxial compressive strength, splitting tensile strength, and shear strength of plain concrete and lightweight aggregate concrete are significantly increased, with the improved percentages of 35.63%, 43.75%, and 41.29%

To investigate the dynamic performance of self-compacting concrete (SCC), the dynamic uniaxial compression tests at eight different loading strain rates were performed on the ordinary concrete and SCC cubic specimens. Based on the tests, the compression failure patterns and stress–strain curves of both kinds of concrete were obtained. The results show that SCC performs more brittle than
An improved passive confining pressure SHPB method was used to study the dynamic mechanical behaviors of asphalt concrete under quasi-one dimensional strain state. The effect of confining jacket material and its geometrical sizes on the confining pressure were
