碩士 === 國立臺北科技大學 === 土木與防災研究所 === 95 === A parametric analysis on the structural behaviors of three low-to-midrise concrete buildings during past earthquakes was conducted in this study using the computer program ETABS. The stiffnesses and damping ratios of these structures as well as different modeling. Pechniques were examined to observe the sensitivity of the results to each individual factor. Comparisons were made primarily on roof accelerations obtained via structural analysis and those provided by the Central Weather Bureau. By adjusting the above parameters, an optimized structural model can be found for each building. In addition, the variation of element stiffness could be used as an index for structural damages.
