摘要：Dynamic experiment of concrete in tension subjected to various strain rates is carried out on the servo fatigue machine and the experiment results are analyzed. It is found that tensile strength of concrete promotes approximately linear with the logarithm of strain rate, elastic modulus and energy absorption capacity of concrete increase with the increasing of strain rate and Poisson's ratio of concrete is less sensitive to the strain rate. Finally, the relationship between tensile strength and strain rate is proposed and the results are compared with some results of previous researchers.
