This experiment involved gradually inducing damage until collapse to verify the building's margin of safety, etc. As the test specimen, a 1/3-scale model of an 18-story steel-frame building designed and constructed in the 1980s to 1990s was fabricated (1×3 spans, plan dimensions 5×6 m, height 25.3 m, weight approximately 420 tons). This test specimen was the world's largest of its kind for shake table testing. When the simulated earthquake motions developed for the “Nankai Trough Triple Earthquake” were applied to the test specimen, collapse modes similar to those expected were confirmed., データ取得:2013年, Data acquisition period : 2013, お問い合わせ:asebi@bosai.go.jp, inquiry: asebi@bosai.go.jp}, title = {鉄骨造高層建物の崩壊余裕度定量化}, year = {2015}, yomi = {ボウサイカガクギジュツケンキュウショ} }
