In considering DEC, it is necessary to clarify the possible failure modes of the structures and their mechanism under the extreme loadings. Because piping systems are one of the representative components of NPP, and there is a possibility to failure at seismic events, the authors conducted an experimental investigation on failure modes and their mechanisms of piping systems under excessive seismic loads.\nThe experiments are categorized into the fundamental plate tests and pipe component tests. In this paper, the\u0027 results of the pipe component tests would be described. In the pipe component tests, the authors used piping specimens constituted with one steel elbow and a weight. Though the input acceleration level was much over the allowable level to prevent collapse failure by the seismic design, the failure mode obtained by the excitation tests were mainly the fatigue failure. The reduction of the dominant frequency and the increase of the hysteresis damping were clearly observed in the high-level input acceleration due to the plastic deformation, and they affected the specimens\u0027 vibration response greatly.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "AMER SOC MECHANICAL ENGINEERS", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1115/PVP2015-45711"}}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Izumi Nakamura", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Naoto Kasahara", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "EXCITATION TESTS ON ELBOW PIPE SPECIMENS TO INVESTIGATE FAILURE BEHAVIOR UNDER EXCESSIVE SEISMIC LOADS", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "EXCITATION TESTS ON ELBOW PIPE SPECIMENS TO INVESTIGATE FAILURE BEHAVIOR UNDER EXCESSIVE SEISMIC LOADS", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4806", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4806", "relation": {}, "relation_version_is_last": true, "title": ["EXCITATION TESTS ON ELBOW PIPE SPECIMENS TO INVESTIGATE FAILURE BEHAVIOR UNDER EXCESSIVE SEISMIC LOADS"], "weko_shared_id": -1}
