Özet:

 

This paper deals with the combined effects of wind and earthquake on the dynamic response of a cantilever structure. It is mainly composed of the core-structure, multi-outriggers with magneto-rheological (MR) dampers localized at different levels along of the structure and perimeter columns. These control devices are semi-active in nature and exhibit a nonlinear behaviour. One of their interesting characteristics is their ability to add supplementary energy dissipation to the structural system. Exposed to combined wind and earthquake loads, the core-structure is modelled using a Timoshenko cantilever beam. The stochastic approach based on the statistic properties is employed to estimate the degree excitations of the two natural hazards. The peak Root-Mean-Square (RMS) are evaluated to quantify the optimal location of damped outriggers. Defined as the control algorithm based on human reasoning, the Fuzzy logic is used to select the appropriate current that feeds the control devices. The obtained results indicate that the application of the fuzzy logic further minimizes the effects of bending-moment and shear force. All of these enhance the performance of the whole structural response and lead to a significantly reduction of excessive vibration to an acceptable level.
