碩士 === 國立交通大學 === 土木工程系 === 87 === The main purpose of this research is to study the difference between the measurement response and theoretical answer using a 5 story scale-down steel structure as model. The dynamic parameters of the structure and response of each floor can be identified either by modal test or by experiment using shaking table. Using all the dynamic parameters obtained, A dynamic model can be set up to predict the response of the structure under certain earthquake. The prediction is compared with the measurement by shaking table to verify the dynamic parameters. Using code 'SAP90' and 'ETABS', the difference of dynamic parameters are also calculated either by two-dimensional model or three-dimensional model. The comparison result between the theoretical calculation and modal testing is discussed in this study.
