| Summary: | 碩士 === 國立中興大學 === 土木工程學系 === 93 === Building structures are typically designed using the assumption that the floor system serve as rigid diaphragm. The study discussed the dynamic response of R.C. structures based on the hypothesis of rigid diaphragm and non-rigid diaphragm, in comparison with the influence of earthquake response from non-rigid diaphragm design.
The study used ETABS to set structure models, and analyzed the buildings by response spectrum analysis of different stories and different spans. Besides, it discussed whether buildings could have distinct difference or not from rigid and non-rigid diaphragm design when structures include R.C. wall.
The results of this study show that rigid diaphragm assumption can not obtain structural correct response when structure include R.C. wall, and shear of column from analytical result is dangerous. In order to consider effect caused by floor deformation, non-rigid diaphragm analysis is recommended.
