Text of Note

Wind induced vibration in tall structures is an important problem that needs effective and practical solutions. TMDs in either passive, active or semi-active form are the most common devices used to reduce wind-induced vibration. The objective of this research is to investigate and develop an effective model of a single multi degree of freedom (MDOF) active pendulum tuned mass damper (APTMD) controlled by hydraulic system in order to mitigate the dynamic response of the proposed tall building perturbed by wind loads in different directions. The proposed APTMD can be tuned to the first three dominant frequencies of the targeted structure in three directions (X, Y, γ) simultaneously and add damping to the corresponding modes. Another design requirement of the APTMD is the capability of adjusting its properties (stiffness and damping) to compensate for the detuning occurred due to the varying operating conditions such as an environment, or imposed loading. These supplemental damping devices offer attractive means to protect tall buildings against natural hazards and make a genuine contribution to the building sway, which has such a great economic and social effects.
