| Abstract: | In order to investigate the mechanical properties of concrete under dynamic loas,compressive experiments of concrete specimens(C40) are carried out on MTS,with the uniaxial strain rate ranging from 10-5 s-1 to 10-2 s-1.The compressive properties of concrete under different stain rates,which include compressive strength,elastic modulus,peak strain and Poisson's ratio,are studied systematically.The effect law of strain rates on the compressive strength,elastic modulus and etc.of concrete are analyzed.The test... |
