This　paper　presents　an　experimental　program　designed　to　investigate　strain　rate　effects　on　the　bond　behavior　of　grouted　splice　sleeves　connected　with　deformed　steel　bars.　Thirty-six　grouted　splice　sleeve　specimens　with　different　anchorage　lengths　were　designed　and　tested　under　direct　dynamic　tensile　loads　with　four　loading　strain　rates　(10−3,　10−1,　10°　and　10+1　s−1).　Strain　gauges　were　employed　to　record　the　strain　of　the　sleeve　and　rebar.　The　failure　modes　and　the　dynamic　bond-slip　relationships　of　specimens　were　obtained.　The　results　show　that　the　bond　force　capacity　increases　with　an　increase　in　the　strain　rate.　However,　the　failure　mode　shifts　from　the　steel　bar　fracture　towards　steel　bar　pullout　as　the　strain　rate　increases.　The　mechanisms　of　a　dynamic　load　transmission　are　described　based　on　the　experimental　results.　A　dynamic　analytical　procedure　incorporating　the　strain　rate　effects　was　developed　to　predict　the　bond　force-slip　relationships　and　was　validated　by　comparing　the　experimental　bond　force-slip　curves.　The　shifting　of　failure　modes　was　attributed　to　the　damage　aggravation　effects　of　the　grouted　mortar,　which　led　to　a　reduced　effective　anchorage　length　and　a　steel　bar　pullout　failure　mode　at　high　strain　rates.　In　addition,　based　on　the　proposed　analytical　model,　the　required　anchorage　length　of　grouted　splice　sleeves　at　different　strain　rates　was　calculated　and　an　empirical　model　was　developed　to　determine　the　critical　embedment　length　to　facilitate　engineering　design.　©　2023
