Abstract：

In　order　to　investigate　the　influence　near-fault　ground　motion　(NFGM)　on　seismic　performance　of　the　elastic　restraint　system　(ERS)　and　the　viscous　damper　system　(VDS)　of　cable-stayed　bridge　(CSB).　A　number　of　NFGMs　from　different　earthquake　events　were　selected　as　excitations.　The　nonlinear　time　history　analysis　are　carried　out　based　on　the　finite　element　model　of　a　long　span　CSB.　The　seismic　analysis　studies　show　NFGMs　of　the　ChiChi　earthquake　lead　to　larger　seismic　response　than　the　Imperial　Valley　earthquake.　The　NFGMs　with　large　velocity　pulse　may　enlarge　both　the　internal　force　and　deformation　response　of　the　ERS　and　VDS.　The　VDS　can　always　get　a　better　performance　than　the　floating　system　(FS)　under　NFGMs　from　different　earthquake　events.　However,　the　ERS　may　cause　larger　internal　forces　responses　when　suffered　from　NFGMs　of　ChiChi　earthquake　with　or　without　velocity　pulse.　©　2018　IEEE.
