Description
Summary:碩士 === 中原大學 === 土木工程研究所 === 102 === The objective of this study is to assess the effectiveness of tuned mass dampers (TMD), tuned liquid column dampers (TLCD) and improved tuned liquid column dampers (ITLCD) for vibration control of building structures under seismic loads. The structural system is developed by deriving the equations of motion for a building structure with a damper. Based on these governing equations, the optimal parameters of the damper are determined using the genetic algorithm in the frequency domain analysis. Under considerations of these optimal parameters, the time domain analysis is conducted to calculate the time histories of structural response for three types of systems: without control, passive control and active control, i.e., fuzzy sliding mode control. The results indicate that the effectiveness of the ITLCD is relatively higher than that of the TMD, whereas the effectiveness of the TLCD is comparatively insignificant.
