Seismic evaluations are conducted through the experimental investigations and dynamic response analyses. Experimental investigations were carried out on one-bay two-story RC frames retrofitted by thick hybrid wall technique. One specimen is a non-retrofitted benchmark specimen to verify the effectiveness of the retrofit method. Three specimens were retrofitted by thick hybrid wing-wall with different retrofit schemes and one specimen was retrofitted by thick hybrid panel-wall. In the proposed retrofit technique, channel-shaped steel plates jacket the boundary columns of RC frame and extend to the bay of the frame through the additional steel plates. The steel plates at both sides of frame are stitched together by means of PC bars (high-strength bolts) crossing the body of thick hybrid wall. The depth of wing-wall can be readily decided to obtain a desired lateral strength and stiffness. The experimental investigations proved the effectiveness of the proposed retrofit technique. The design frameworks for calculations the lateral strengths of the retrofitted column are suggested. To find out the seismic response of the building retrofitted by thick hybrid wall, an existing soft-first-story building in Okinawa, where the soft-first-story buildings are commonly built, is selected. The seismic evaluation of the building is implemented based on the retrofit guideline by Japan Building Disaster Prevention Association and nonlinear dynamic response analyses. It was assumed that the building was retrofitted by conventional method (shear wall) and by thick hybrid wall. Nonlinear dynamic analyses were implemented under three earthquake excitations including Taft, Kobe and El Centro scaled to two levels of intensity. Seismic performance of the building retrofitted by thick hybrid wall exhibited a superior performance in compared to conventional one.","subitem_description_type":"Other"},{"subitem_description":"学位論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"en","subitem_1522300316516":"Javadi, Pasha"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/18527"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2009-08","bibliographicIssueDateType":"Issued"},"bibliographicPageEnd":"95","bibliographicPageStart":"1"}]},"item_1617187087799":{"attribute_name":"Dissertation Number","attribute_value_mlt":[{"subitem_1551256171004":"甲第175号"}]},"item_1617187112279":{"attribute_name":"Degree Name","attribute_value_mlt":[{"subitem_1551256126428":"博士（学術）","subitem_1551256129013":"ja"}]},"item_1617187136212":{"attribute_name":"Date Granted","attribute_value_mlt":[{"subitem_1551256096004":"2009-09-11"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"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":"riken175.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2005707/files/riken175.pdf"},"version_id":"d40547a8-6b73-4eea-966d-e96abeb1cf05"}]},"item_1617944105607":{"attribute_name":"Degree Grantor","attribute_value_mlt":[{"subitem_1551256015892":[{"subitem_1551256027296":"18001","subitem_1551256029891":"kakenhi"}],"subitem_1551256037922":[{"subitem_1551256042287":"琉球大学","subitem_1551256047619":"ja"}]}]},"item_title":"Seismic Evaluation of Soft-first-story RC Buildings Retrofitted by Thick Hybrid Wall Technique","item_type_id":"15","owner":"1","path":["1642838161450","1642838411479"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-12-15"},"publish_date":"2021-12-15","publish_status":"0","recid":"2005707","relation_version_is_last":true,"title":["Seismic Evaluation of Soft-first-story RC Buildings Retrofitted by Thick Hybrid Wall Technique"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T02:51:04.729663+00:00"}
