The　response　of　high-rise　structure　under　long　period　ground　motion　(LPGM)　gets　more　and　more　attention　after　311　earthquake＇　in　Japan.　To　investigate　the　dynamic　response　and　failure　characteristics　of　frame　structure,　a　1/4　scale　model　of　a　20　layers　RC　frame　subjected　to　LPGM　was　tested　on　E-defense　shaking　table　by　Japanese　scholars　recently.　The　typical　experimental　results　were　introduced　by　firstly.　And　then　the　nonlinear　behavior　observed　in　the　test　was　reproduced　by　using　the　finite　element　analysis　(FEM)　software　SNAP,　in　which　the　behavior　of　beam　and　column　were　modeled　by　plastic　hinge　and　fiber　models　respectively.　Based　on　the　FEM　model,　the　two　particular　characteristics　(long　duration　and　vast　displacement　response)　of　high-rise　frame　structure　subjected　to　LPGM　were　simulated.　The　two　characteristics　caused　notable　cumulative　damage　on　beam　end,　which　was　considered　by　using　a　revised　plastic　hinge　model　in　FEM　simulation.　The　comparative　analysis　method　was　verified　by　the　good　agreements　of　the　tested　and　simulated　results.
