During　the　collapse　analysis　of　reinforced　concrete　structures,　the　impact　action　between　concrete　blocks　is　significant　in　the　process　of　the　large　deformation.　Based　on　the　impulse-response　rigidity,　the　method　treating　impact　action　between　concrete　blocks　is　presented,　in　which　the　rotation　of　the　blocks　is　considered.　The　behavior　of　the　different　impact　modes　between　concrete　blocks　is　studied　based　on　the　experiments　and　the　numerical　tests.　Firstly,　the　face-to-face　central　impact　experiments　with　30　couple　of　concrete　cubic　blocks　are　performed　using　a　pendulum　test　system　and　a　drop　weight　test　system.　Then　the　experimental　processes　are　recurred　by　the　finite　element　code　LS-DYNA.　And　the　extended　and　the　supplementary　numerical　tests　for　face-to-face　central　impact　are　carried　out　respectively,　considering　the　change　of　the　experimental　parameters　and　the　other　parameters　which　are　not　designed　in　the　experiments.　Furthermore,　the　numerical　tests　for　face-to-face　noncentral　impact,　line-to-face　impact,　point-to-face　impact,　line-to-line　impact　and　the　numerical　tests　that　are　to　study　the　influence　of　the　shape　of　concrete　blocks　are　performed.　In　the　end,　the　impulse　models　describing　the　behavior　of　the　different　impact　modes　between　concrete　blocks　are　derived　from　the　results　of　the　experiments　and　the　numerical　tests.
