new emergency/permanent seismic retrofit technique for existing RC columns, in which aramid fiber belts are pre-tensioned and used as external transverse reinforcement, is proposed in this investigation.This retrofit is a diy method, which does not require heavy machineiy.This seismic retrofit technique is proposed by the attention to this fact as emergency reinforcement right after the earthquake disaster. By experimental cyclic loading tests of retrofitted RC columns, it was proven to be alterable for the flexural yield mode that is rich in the ductility after retrofit, in respect of brittle shear, failure mode before retrofit.And, the seismic performance was also possible, if the thin steel plates were put on the surfac&of the RC columns under high axial force whose ratio was 0.6.The axial compression tests of concrete columns using the pre-tensioned aramid fiber belt were carried out. The results showed that both the compressive strength and ductility were improved together with the introduction of prestress. It was proven that the emergency retrofit was effective for the recoveiy of lateral capacity and ductility of damaged RC columns by both axial compression and cyclic loading tests.It was confirmed to be effective more and more, if the tensile force was introduced into the aramid fiber belt, and the thin steel plates were utilized.","subitem_description_type":"Other"},{"subitem_description":"未公開：P.6以降(別刷論文のため)","subitem_description_type":"Other"},{"subitem_description":"研究報告書","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"山川哲雄"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/14008"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"NCID","subitem_1522646572813":"BA74216859"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2004-05","bibliographicIssueDateType":"Issued"}}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"13555159.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2005158/files/13555159.pdf"},"version_id":"5d3a0879-f5a4-4ce9-a46c-0c6b4932ef30"}]},"item_title":"連続繊維ベルトを外帯筋状に巻き付けプレストレスを導入したRC柱の耐震・応急補強法","item_type_id":"15","owner":"1","path":["1642838403123","1642838406845"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-12-16"},"publish_date":"2009-12-16","publish_status":"0","recid":"2005158","relation_version_is_last":true,"title":["連続繊維ベルトを外帯筋状に巻き付けプレストレスを導入したRC柱の耐震・応急補強法"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T02:30:55.309081+00:00"}
