| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 93 === Abstract
Udwadia et al. proposed a unique system identification theory for a shear building model by Laplace transform. This technique can more directly identify physical parameters of shear building than Izuru Takewaki’s system identification theory by FFT. Research had found some errors between idntified and preassigned values by Udwadia’s theory. This paper not only reformulates Udwadia’s system identification formula but also discusses error source and sensitive problems. The more discussions take two real response datas from shaking table experiment to identify physical parameters of building.
