Suspender　is　the　main　component　of　half　through　or　through　arch　bridges,　connecting　decks　to　arch　ribs,　transferring　dead　loads　and　live　loads　from　the　decks　to　the　arch　ribs,　in　order　to　realize　the　spanning　function　of　arch　bridges.　Any　failure　of　suspenders　may　cause　collapse　of　deck　system　and　partial　or　whole　damage　of　arch　ribs.　Therefore,　it　should　be　ensured　that　suspenders　must　be　strong　enough　in　bridge＇s　service　life,　or　avoid　the　occurrence　of　any　disastrous　accident　when　suspender　breakage　happens.　But　the　existing　design　code　does　not　consider　the　reacting　force　generated　by　suspenders　breakage,　nor　does　it　limit　the　internal　force　and　deformation　in　girders　when　inclined　cable　breakaae　happens　as　that　in　the　＂Guidelines　for　Design　of　Highway　Cable-Stayed　Bridge＂.Taking　Shenzhen　North　Railway　Station　Bridge　as　an　engineering　background　and　using　ANSYS/LS-DYNA　as　FEM　analysis　tool,　this　paper　makes　a　dynamic-contact　and　impact-simulation　to　the　breakage　process　of　a　short　double-suspender.　The　FEM　simulation　results　indicate　that　stresses　in　certain　suspenders　may　exceed　their　allowable　stress　due　to　the　breakage　of　the　short　suspenders　while　others　are　not　subjected　to　breakage;　and　that　the　girder　may　be　destroyed　and　the　deck　system　may　be　collapsed　due　to　its　significant　vertical　deflection.
