摘要：

A　single　rib　concrete-filled　steel　tubular　arch　bridge　is　adopted　while　a　TMD　system　is　to　be　installed　on　top　of　the　main　arch　rib　according　to　the　analyzing　results　of　this　prototype＇s　dynamic　characteristics　simulated　with　FEM　software　Midas.　Researches　on　the　optimal　parameter　values　of　the　TMD　are　carried　out　respectively　with　and　without　the　damping　of　the　main　structure.　The　performance　of　TMD　on　seismic　control　is　analyzed　based　on　the　comparison　of　the　displacements　of　the　main　arch　bridge　top　under　3　different　seismic　loads　between　the　original　structure　and　the　TMD-installed　structure.
