In order to joint the wall panel and the column easily, anchors to the column of horizontal reinforcements of the wall panel are omitted in the system. An ultimate strength of the system is provided by adding each shear force of the wall panel and columns. However, the strength of the wall panel is not able to obtain by the general strength calculation formulas since wall panels of the system do not have any flexural reinforcements such as main reinforcements of columns. Therefore, a strength calculation method based on a new truss-arch theory was developed in this paper. The calculation method evaluates the ultimate strength stood on stress balance; hence, the strength shows flexural strength or shear strength. A truss mechanism of the calculation method involves particular stress of horizontal reinforcements of the system that become large on diagonal lines of the wall panels, and that is 0 at both the ends. In the portion with the stress change of horizontal reinforcements, tensile force of the horizontal reinforcements is transmitted to concrete strut by bond resistance. The tensile force, the compressive force of the concrete struts and the tensile force of vertical reinforcements satisfies equilibrium conditions. Axial forces, reverse bending moments, and constraint forces provided by the vertical reinforcements have an effect on an arch mechanism of the calculation method. After the calculation method for 1-storey wall panels has been proposed, it is extended to a method for multi-storey wall panels which external force acts on at plural height. Loading tests of single and two-story wall panels were conducted to investigate compatibility of the calculation method. As a result, the calculated values of flexural failures and shear failures were in good agreement with the experiments. After clarifying the strength calculation method of the wall panels, loading tests of the wall systems of two types constituted of the wall panel and columns were conducted. One is resistance strength systems which prevent the sliding failure of a vertical joint between wall panels and columns, and the other is resistance ductility systems which permit of sliding at the vertical joints. It was clear that precast multi-story wall systems which permit of sliding at the vertical joints show high deformation performance as a result of the experiments. The study revealed the ultimate strength of the system is able to evaluate by adding the strength of wall panel and the shear force of column.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_81_dissertation_number_13":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"乙第79号"}]},"item_81_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15118/00005118","subitem_identifier_reg_type":"JaLC"}]},"item_81_subject_9":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"524","subitem_subject_scheme":"NDC"}]},"item_81_text_12":{"attribute_name":"学位の種別","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"論文博士"}]},"item_81_text_14":{"attribute_name":"報告番号","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"乙第79号"}]},"item_81_text_15":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"博乙第79号"}]},"item_81_version_type_24":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"小坂, 英之","creatorNameLang":"ja"},{"creatorName":"KOSAKA, Hideyuki","creatorNameLang":"en"},{"creatorName":"コサカ, ヒデユキ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-15"}],"displaytype":"detail","filename":"B79.pdf","filesize":[{"value":"2.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"B79","objectType":"fulltext","url":"https://muroran-it.repo.nii.ac.jp/record/5127/files/B79.pdf"},"version_id":"82d675be-308e-4af3-9d68-e7554fe48874"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-15"}],"displaytype":"detail","filename":"B79_summary.pdf","filesize":[{"value":"379.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"B79_summary","objectType":"abstract","url":"https://muroran-it.repo.nii.ac.jp/record/5127/files/B79_summary.pdf"},"version_id":"4da1125a-3539-4690-8990-d8c636ae7e13"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"壁板と柱の分離施工を容易とする新しい耐震壁システムの開発研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"壁板と柱の分離施工を容易とする新しい耐震壁システムの開発研究","subitem_title_language":"ja"}]},"item_type_id":"81","owner":"18","path":["227"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-12-04"},"publish_date":"2014-12-04","publish_status":"0","recid":"5127","relation_version_is_last":true,"title":["壁板と柱の分離施工を容易とする新しい耐震壁システムの開発研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-11-13T01:25:45.438623+00:00"}
