In the three kinds of constraint ratio (ξ = 0.065, ξ= 0.1025, ξ= 0.205), respectively, by the comparative analysis of 55 prism specimens using CFRP confined concrete(strain ratses are 10-5/s-1, 10-4/s-1, 10-3/s-1 and 10-2/s-1), the stress-strain curves, strength, strain, elastic modulus and Poisson's ratio were studied at different constraints and different strain rate. The results show that: (1) with the strain rate increased,the inflexion strength and ultimate strength of concrete were improved; (2) with the strain rate increased, the static and dynamic elastic modulus increased slightly; (3) Poisson's ratio increased slightly with the growth strain rate.
