Abstract

Numerical simulations of a 20-storey reinforced concrete building are considered to investigate the effectiveness of tuned mass damper (TMD) for control of structures under wind excitation. Many impulsive load cases with different period are used to model wind excitation. The response of the structure with TMD is compared to the response of the structure with increased stiffness and without TMD (this is a traditional design approach). It is demonstrated that the TMD approach is far better than the traditional approach for response reduction of the structure. The effect of TMD's mass on its efficiency is also discussed.
