橋梁端部周辺に着目した大地震時水平衝突応答解析 Horizontal Collision Response Analysis under Strong Earthquake considering around Bridge End Configuration 大島, 俊之 三上, 修一 小倉, 裕介 内田, 裕丈 内堀, 康 longitudinal impact shoclrabs01ving device system for falling prevention of bridge bridge end abutment Finite Element Method 水平衝撃 緩衝材 落橋防止システム 橋端部 橋台 FEM When the strong earthquake occurs and a bridge suffers the longitudinal impact, a superstructure and abutments of a bridge will collide. There is a spatial gap between superstructure and wall of abutment and this gap may effect to accelerate collision speed between them. Then, in this paper, effect of shock-absorbing device to softening the collision is investigated in the cases of simple and continuous girder bridges. And the effect of stiffness of shock-absorbing device, laying-gap length and back-fill ground of a abutment to soften the collision response, is analyzed. Moreover, influence by laying-gap length and an abutments of back-fill ground when colliding was examined. journal article 社団法人 土木学会 2002-08 application/pdf 5 519 526 https://kitami-it.repo.nii.ac.jp/record/7139/files/8668475-5.pdf https://kitami-it.repo.nii.ac.jp/records/7139 jpn open access
