The bridge pier specimen used in this experiment was basically designed in accordance with current standards, but unlike previous specimens, it had rectangular cross-sections (1.8m on a side) with chamfered corners (R=400mm), and in order to increase the ductility of the base of the pier, which is prone to damage, it used “high-ductility fiber-reinforced mortar”  in the mortar instead of normal concrete. The test specimen was 7.5m high, with a base (bottom) measuring 7.0m x 7.0m x 1.8m high, and weighed approximately 310t. The results of the experiment indicated that the damage to the test specimen caused by the shaking was limited to very slight cracks, as had been expected. Subsequently, the same shaking was applied twice, assuming the same level of aftershock, and although the specimen cracked significantly, there was only a small amount of spalling of the highly ductile fiber-reinforced mortar, confirming that the bridge pier using this new material has high seismic resistance.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}, {"subitem_description": "データ取得：2010年　", "subitem_description_language": "ja", "subitem_description_type": "Other"}, {"subitem_description": "Data acquisition period : 2010", "subitem_description_language": "en", "subitem_description_type": "Other"}, {"subitem_description": "お問い合わせ：asebi@bosai.go.jp　", "subitem_description_language": "ja", "subitem_description_type": "Other"}, {"subitem_description": "inquiry： asebi@bosai.go.jp", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "防災科学技術研究所"}, {"subitem_1522300295150": "en", "subitem_1522300316516": "National Research Institute for Earth Science and Disaster Resilience"}]}, "item_1617186660861": {"attribute_name": "Date", "attribute_value_mlt": [{"subitem_1522300695726": "Issued", "subitem_1522300722591": "2012"}]}, "item_1617186783814": {"attribute_name": "識別子", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "10.17598/NIED.0020-E200909"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "dataset", "resourceuri": "http://purl.org/coar/resource_type/c_ddb1"}]}, "item_1617353299429": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_1522306207484": "isIdenticalTo", "subitem_1522306287251": {"subitem_1522306382014": "URI", "subitem_1522306436033": "https://asebi.bosai.go.jp/"}, "subitem_1523320863692": [{"subitem_1523320867455": "en", "subitem_1523320909613": "LOGIN Page for Registered Users"}]}]}, "item_title": "橋梁耐震実験研究 橋梁コンポーネント実験（C1-6実験）", "item_type_id": "40006", "owner": "7", "path": ["1749778844647"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/7180", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2025-06-19"}, "publish_date": "2025-06-19", "publish_status": "0", "recid": "7180", "relation": {}, "relation_version_is_last": true, "title": ["橋梁耐震実験研究 橋梁コンポーネント実験（C1-6実験）"], "weko_shared_id": -1}
