| Popis: | 102 Purpose of this paper is to explore the complex modal analysis tuned mass damper (TMD) of the optimal parameters, and with the vibration between the empirical formula of Den Hartog and genetic algorithms compare the three utility assessment. 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 complex modal analysis 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 one types and 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 complex modal analysis is relatively higher than that of the genetic algorithms in low damping building structure, whereas the effectiveness of the empirical formula of Den Hartog is comparatively insignificant; the effectiveness of the genetic algorithms is relatively higher than that of the empirical formula of Den Hartog in high damping building structure, whereas the effectiveness of the complex modal analysis is comparatively insignificant. |
