Predictions　about　shrinkage　and　creep　of　concrete　are　very　important　for　evaluating　time-dependent　effects　on　structural　performance.　Some　prediction　models　and　formulas　of　concrete　shrinkage　and　creep　have　been　proposed　with　diversity.　However,　the　influence　of　reinforcement　ratio　on　shrinkage　and　creep　of　concrete　has　been　ignored　in　most　prediction　models　and　formulas.　In　this　paper,　the　concrete　shrinkage　and　creep　with　different　ratios　of　reinforcement　were　studied.　Firstly,　the　shrinkage　performance　was　tested　by　the　10　reinforced　concrete　beams　specimens　with　different　reinforcement　ratios　for　200　days.　Meanwhile,　the　creep　performance　was　tested　by　the　5　reinforced　concrete　beams　specimens　with　different　ratios　of　reinforcement　under　sustained　load　for　200　days.　Then,　the　test　results　were　compared　with　the　prediction　models　and　formulas　of　CEB-FIP　90,　ACI　209,　GL　2000　and　JTG　D　62-2004.　At　last,　based　on　ACI　209,　an　improved　prediction　models　and　formulas　of　concrete　shrinkage　and　creep　considering　reinforcement　ratio　was　derived.　The　results　from　improved　prediction　models　and　formulas　of　concrete　shrinkage　and　creep　are　in　good　agreement　with　the　experimental　results.
