低温条件における免震装置の機能確認実験 EXPERIMENT OF FUNCTIONAL CONFIRMATION ON LEAD RUBBER BEARING (LRB) UNDER LOW TEMPERATURE 大島, 俊之 三上, 修一 三上 修一 山崎, 智之 山崎 智之 池永, 雅良 松井, 義孝 久保, 和子 open access LRB Low temperature Experiment It is a important task for a designer to evaluate the vibration characteristics of Lead Rubber Bearing (LRB) when it is used in severe cold environment. That is because the stiffness of rubber increases some how when the temperature decreases less than -10℃. So that the experiment was done in low room temperature up to -30℃ on LRB specimen with different frequencies, amplitudes and vertical forces. Results show that if we take its small changes of vibration characteristics of LRB into account, there is no problem for designer to use LRB up to -30℃ environment. application/pdf 社団法人 土木学会 jpn journal article VoR https://kitami-it.repo.nii.ac.jp/records/7392 構造工学論文集 44A 753 760 https://kitami-it.repo.nii.ac.jp/record/7392/files/8650812-1.pdf application/pdf 998.0 kB 2016-11-22
