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　ordinary　concrete　by　showing　the　diagonal　crack　failure　pattern　of　SCC　at　a　high　strain　rate.　Besides,　with　the　increase　of　loading　strain　rate,　the　peak　compressive　stress　of　SCC　is　slightly　lower　than　that　of　ordinary　concrete,　but　the　increase　of　elastic　modulus　is　slightly　higher　than　that　of　ordinary　concrete.　The　peak　compressive　strains　of　the　two　kinds　of　concrete　are　discrete　under　the　influence　of　loading　strain　rate,　thus　putting　forward　the　relation　equation　for　the　loading　strain　rate　and　peak　compressive　stress　increase　coefficient　of　the　two　kinds　of　concrete.　Besides,　based　on　the　theory　of　elastic-plastic　damage　and　considering　the　dynamic　extension　of　damage,　the　dynamic　constitutive　relation　with　good　applicability　between　ordinary　concrete　and　SCC　was　established.
