Since the stress assessment based on the elastic analysis does not reflect actual response of piping systems including plastic region, rational procedures to estimate the elastic-plastic behavior of piping system\u0027s under a large seismic load are expected to be developed for piping seismic design applications.\nWith the aim of establishing a procedure that takes into account the elastic-plastic behavior effect in the seismic safety estimation of nuclear piping systems, a research activity has been planned. Through the activity, the authors intend to establish two kinds of guidelines; 1) a guideline of a standard analysis procedure to evaluate elastic-plastic behavior of piping systems under extreme seismic loads with rational and conservative margins, and 2) a guideline that provide criteria for the seismic safety assessment of piping systems by the standard analysis to evaluate elastic-plastic behavior established by the above guideline. As the first step of making out the analysis guideline, benchmark analyses are conducted for a pipe element test and a piping system test.\nIn this paper, the outline of the research activity and the preliminary results of benchmark analyses for a pipe element test are described.", "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/PVP2015-45262"}}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Izumi Nakamura", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Masaki Shiratori", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Akihito Otani", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Masaki Morishita", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Tadahiro Shibutani", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Hitoshi Nakamura", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "INTRODUCTION OF A RESEARCH ACTIVITY ON THE SEISMIC SAFETY EVALUATION OF NUCLEAR PIPING SYSTEMS TAKING THE EFFECT OF ELASTIC-PLASTIC BEHAVIOR INTO ACCOUNT", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "INTRODUCTION OF A RESEARCH ACTIVITY ON THE SEISMIC SAFETY EVALUATION OF NUCLEAR PIPING SYSTEMS TAKING THE EFFECT OF ELASTIC-PLASTIC BEHAVIOR INTO ACCOUNT", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4804", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4804", "relation": {}, "relation_version_is_last": true, "title": ["INTRODUCTION OF A RESEARCH ACTIVITY ON THE SEISMIC SAFETY EVALUATION OF NUCLEAR PIPING SYSTEMS TAKING THE EFFECT OF ELASTIC-PLASTIC BEHAVIOR INTO ACCOUNT"], "weko_shared_id": -1}
