観測記録に基づく RC 造建物の振動特性と耐震補強効果に関する調査研究\n—広島工業大学本館棟を対象として— Evaluation of Dynamic Properties and Seismic Resistance of The RC Building \nBefore and After Retro_tting Based on Microtremor Measurements\n—Using The Main O_ce Building in Hiroshima Institute of Technology— 山下, 航平 ヤマシタ, コウヘイ 渡壁, 守正 ワタカベ, モリマサ 久保川, 淳司 クボカワ, ジュンジ 光井, 周平 ミツイ, シュウヘイ 黒河, 真 クロカワ, マコト Kohei, YAMASHITA Morimasa, WATAKABE Junji, KUBOKAWA Shuhei, MITSUI Makoto, KUROKAWA Seismic Reinforcement, Dynamic Characteristics, Microtremor Measurement, Structural Health Monitoring System application/pdf In order to verify the seismic reinforcement e_ect to the RC building quantitatively, Microtremor measurement was carried out for the main building before and after the reinforcement and compared the dynamic characteristics derived from microtremors. As a result, natural frequencies estimated by the microtremor records before the seismic reinforcement are approximately 25~30% bigger than those estimated by these records after the seismic reinforcement. The results show that the reinforcement method signi_cantly increases the sti_ness of a RC building. Furthermore, this paper presents the Structural Health Monitoring （SHM） system using Internet of Things （IoT） to improve for the earthquake disaster reduction and maintainability of buildings. departmental bulletin paper 広島工業大学 2023-02-05 VoR application/pdf 広島工業大学紀要. 研究編 57 107 114 AA11599110 1346-9975 https://it-hiroshima.repo.nii.ac.jp/record/1179/files/research57_107-114.pdf https://it-hiroshima.repo.nii.ac.jp/records/1179 jpn
