First, behavior of the soil surrounding the piles is nonlinear. Second, large inertial forces are generated in the soil around the pile heads, causing separation between the soil and pile. In this paper, a new approach is presented to overcome material nonlinearity of the soil as well as geometrical nonlinearity arising due to separation. The analysis is performed in two steps. To account for material nonlinearity, equivalent linearization is used in conjunction with a hyperbolic model of the soil. The hyperbolic model defines the nonlinear stress-strain relationship of the soil. To deal with separation, a Winkler soil model is used. The dynamic stiffness reproduced by the soil model is changed according to the degree of separation. Depending on the level of excitation, different cases of separation arise which are investigated with skeleton curves. It has been found that due to separation, dynamic response of the soil-pile system increases whereas the dynamic stiffness decreases significantly.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"rights: 社団法人地盤工学会\nrights: 本文データは学協会の許諾に基づきCiNiiから複製したものである\nrelation: IsVersionOf: http://ci.nii.ac.jp/naid/110004781713/","subitem_description_type":"Other"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人地盤工学会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00380806","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"MAHESHWARI, B.K."},{"subitem_text_value":"WATANABE, H."}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1003844"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"埼玉大学"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Department of Earthquake Engineering, Indian Institute of Technology Roorkee:Department of Civil Engineering, Saitama University"},{"subitem_text_value":"Department of Civil Engineering, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2006-8"}]},"item_119_version_type_28":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"MAHESHWARI, B.K."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"WATANABE, H."}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1003844.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1003844.pdf","url":"https://sucra.repo.nii.ac.jp/record/14167/files/A1003844.pdf"},"version_id":"69846e89-8dea-440a-9cb4-620c1c58bcbf"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"dynamic analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"dynamic stiffness","subitem_subject_scheme":"Other"},{"subitem_subject":"nonlinear response","subitem_subject_scheme":"Other"},{"subitem_subject":"pile foundations","subitem_subject_scheme":"Other"},{"subitem_subject":"separation","subitem_subject_scheme":"Other"},{"subitem_subject":"soil-pile interface","subitem_subject_scheme":"Other"},{"subitem_subject":"Winkler soil model","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"NONLINEAR DYNAMIC BEHAVIOR OF PILE FOUNDATIONS : EFFECTS OF SEPARATION AT THE SOIL-PILE INTERFACE","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"NONLINEAR DYNAMIC BEHAVIOR OF PILE FOUNDATIONS : EFFECTS OF SEPARATION AT THE SOIL-PILE INTERFACE"}]},"item_type_id":"119","owner":"3","path":["641"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-10-20"},"publish_date":"2009-10-20","publish_status":"0","recid":"14167","relation_version_is_last":true,"title":["NONLINEAR DYNAMIC BEHAVIOR OF PILE FOUNDATIONS : EFFECTS OF SEPARATION AT THE SOIL-PILE INTERFACE"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:09:05.686980+00:00"}
