| Abstract: | The dynamic compressive test of concrete specimens,due to load histories of 0,30%,50%and 75% ultimate strengths,is carried out on the static-dynamic triaxial test system with the strain rates ranging from 10-5 s-1 to 10-2 s-1.The strain-stress full curves,the compressive strength,the initial elastic modulus and the critical strain of concrete at different strain rates and load histories are analyzed and the effects of strain rates and load histories on these behaviors are studied.Experimental results show t... |
