A two-point loading test of a composite girder was carried out to verify the numerical modeling by comparing the experimental and numerical results. Then, a parametric study was performed using finite element analyses to investigate the effect of concrete crushing on the flexural strength of composite girders constructed using SM570 grade steel. Observations made by comparison of the ultimate flexural strength obtained from the experimental and numerical results with that according to the AASHTO and Eurocode show that the existing reduction factor equations are conservative and can be relaxed when the strength is controlled by crushing of concrete slab. A new reduction factor for the ultimate flexural strength for composite I-girders under positive bending is proposed.\n密実な断面を持つ合成鋼桁の終局的なたわみ強度は,終局たわみ強度の減少係数を発展させるために,実験的研究と弾塑性有限変位解析により審査された。実験結果と計算結果を比較して数学モデルを実証するために,合成桁の2点載荷試験が行われた。そして,SM570級の鋼材を使って構築された合成桁のたわみ強度に関わるコンクリート破壊の影響を調べるために,有限要素解析を使ってパラメトリック解析が行われた。AASHTOとユーロコードに従って実験結果と計算結果から得られた終局たわみ強度の比較より得られた見解は,現存の減少係数が保守的であり,コンクリートスラブの破壊によりその強さが制御されると軽減されることを示している。正の曲げを受ける合成I桁に対する終局たわみ強度の新しい減少係数が提案された。 (翻訳著者抄録)","subitem_description_type":"Abstract"}]},"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":"社団法人土木学会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18806023","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[著者版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"OKUI, Yoshiaki"},{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"&EMPTY&"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1003215"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"埼玉大学大学院理工学研究科環境科学・社会基盤部門"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Lead Structural EngineerChiyoda Corp."},{"subitem_text_value":"Department of Civil and Environmental Engineering, Saitama University"},{"subitem_text_value":"Nippon Expressway Res.
