損傷RC柱の打撃法による損傷評価に関する研究 Study on Damage Evaluation of Damage RC Pier by Using Impact Testing 山崎, 智之 大島, 俊之 三上, 修一 太田, 雅仁 damaged pier integrity diagnosis vibration characteristics echo wave Experimental study using nondestructive testing method on RC pier model is discussed in this paper. Modal vibration method and pulse echo method are used to detect internal damages as a nondestructive testing. Change of modal characteristics and reflection waves returned from the damage are analyzed to identify the scale of damage. Hysteretic absorption energy due to elastic-plastic deformation is a main parameter to evaluation the changes of frequency and damping. And by echo waves we could identify the location of internal crack of RC pier. application/pdf journal article 社団法人 土木学会 application/pdf 構造工学論文集 45A 337 345 https://kitami-it.repo.nii.ac.jp/record/7406/files/8654428-4.pdf https://kitami-it.repo.nii.ac.jp/records/7406 jpn open access
