In　order　to　solve　the　problem　of　seismic　design　of　continuous　beam　bridge　in　which　the　longitudinal　seismic　inertia　force　is　only　carried　by　the　fixed　pier，the　seismic　potential　of　the　movable　pier　is　fully　exerted　with　the　same　section　as　the　fixed　pier.　Based　on　the　principle　of　wrap　rope，the　mass　rotation　wrap　rope　device　excited　by　additional　mass　inertia　force　is　developed　to　realize　the　cooperative　force　of　fixed　pier　and　movable　pier　and　limit　the　relative　displacement　of　beam　end.　Based　on　the　working　principle　and　structural　characteristics　of　the　device，the　restoring　force　model　of　the　device　is　proposed，and　through　a　3-span　regular　continuous　beam　bridge，the　finite　element　model　of　the　whole　bridge　is　established.　The　effects　of　additional　mass，friction　coefficient　and　initial　relaxation　coefficient　on　the　vibration　reduction　performance　of　continuous　beam　bridge　are　systematically　analyzed.　The　results　show　that　the　effect　of　mass　rotation　wrap　rope　device　on　reducing　the　seismic　response　of　fixed　pier　and　lifting　the　movable　pier　to　participate　in　the　longitudinal　whole　cooperative　force　of　continuous　beam　bridge　is　obvious.　The　influence　of　parameters　of　different　seismic　wave　input　characteristics　is　slightly　different，but　reasonable　design　parameters　of　the　device　will　produce　a　more　obvious　effect　of　shock　absorption.　©　2024　Nanjing　University　of　Aeronautics　an　Astronautics.　All　rights　reserved.
