Based　on　the　Luozhou　bridge　in　Fuzhou,　the　effect　of　tower　longitudinal　stiffness　on　static　performance　of　self-anchored　suspension　bridge　with　multi-tower　are　researched　by　using　FEM.　The　results　show　that　the　tower　longitudinal　stiffness　has　a　great　influence　on　the　mechanical　behavior　of　it.　Changes　in　the　tower　longitudinal　stiffness　will　not　only　lead　to　the　tower　inner　force　and　deformation　change,　but　also　the　distribution　of　inner　force　and　deformation　of　the　overall　structure　are　significantly　affected.　Increasing　the　tower　longitudinal　stiffness,　especially　the　increase　in　the　mid-tower　longitudinal　stiffness　is　an　effective　way　to　improve　the　vertical　stiffness　of　self-anchored　suspension　bridge　with　multi-tower.　©　2013　Taylor　&　Francis　Group,　London.
