内容記述 | Few previous studies have estimated the damping ratio of buildings using seismic ground motion, due to the difficulty of making estimations. The Random Decrement (RD) technique is applied to vibration observation data of a building excited by a weak seismic ground motion. Estimates are made of the damping ratio and natural frequency for 7 buildings of the University of Tokyo. Data are obtained with IT strong-motion seismographs installed inside buildings of the University. Then, a Single Degree Of Freedom (SDOF) system analysis is carried out. The simplest building for which the primary mode dominated is selected, and parameters estimated using the RD technique are sent to the SDOF system. The results obtained with the RD technique and the SDOF system analysis are compared, and the accuracy of the estimated data are verified. Finally, problems related to establishing the method for estimating the damping ratio using weak seismic ground motion are discussed. | |||||
