Abstract

Todays, structural analysis techniques have been improved, and structural engineers are able to build High-Rise Buildings. In these structures, it should be noted that elevation is often accompanied by an increase in the softness, which increases the sensitivity of the structure to dynamic forces such as wind. The purpose of the present study is to study the wind-induced Vibrations on Tall Buildings, taking into account the effects of Vortices created by the fluid flow and also the controlling this phenomena. To this end, the governing equations of the structure, the fluid flow and the tuned-mass damper are first introduced, and their coefficient values are extracted according to the characteristics of ACT skyscraper and solved using a program coded in MATLAB. After validating the results, the effects of wind loads are investigated by considering vortex effects as well as different wind velocity profiles; and the results are compared with the case where no Vortices are considered and the optimal operating range of TMD is defined. At last, parametric study on mass ratio and wind speeds are presented.
