In　actual　engineering　structures,　static　and　dynamic　loads　frequently　coexist.　To　enhance　the　physical　and　mechanical　properties　of　engineered　cementitious　composite　(ECC)　materials　and　improve　their　durability,　this　study　prepared　six　types　of　steel-polyethylene　hybrid　fiber　reinforced　engineered　cementitious　composites　(ST/PE-HFRECC)　by　incorporating　varying　volume　contents　of　steel　and　polyethylene　(PE)　fibers.　Dynamic　compression　tests　were　conducted　at　three　loading　rates　using　a　split　Hopkinson　pressure　bar　capable　of　pre-applied　static　loads.　The　experimental　results　are　summarized　as　follows:　(1)　The　dynamic　compressive　strength,　dynamic　peak　strain,　pre-peak　toughness,　and　dynamic　increase　factor　(DIF)　of　ST/PE-HFRECC　exhibit　significant　strain　rate　strengthening　effects　under　combined　static　and　dynamic　loading.　Specifically,　a　pre-applied　static　load　at　the　15　%　level　can　enhance　the　dynamic　compressive　strength　of　the　material.　Moreover,　under　the　30　%　and　45　%　pre-applied　static　loads,　the　increase　in　the　dynamic　peak　strain　becomes　more　pronounced.　The　DIF　reaches　its　peak　value　when　the　pre-applied　static　load　is　at　the　15　%　level.　(2)　The　damage　extent　of　the　specimens　increases　with　higher　pre-static　load　levels.　Steel　fibers　primarily　bridge　large　cracks,　while　PE　fibers　bridge　micro-cracks.　(3)　Pre-applied　static　loads　exhibit　both　weakening　and　strengthening　effects　on　the　dynamic　mechanical　properties　of　ST/PE-HFRECC.　Consequently,　studying　the　dynamic　mechanical　behavior　of　hybrid　fiber-cement　composites　under　static　and　dynamic　loading　conditions　is　not　only　beneficial　for　evaluating　structural　safety　but　also　provides　crucial　insights　for　the　design　of　structural　components.　©　2025　Elsevier　Ltd
