Response control of buildings using tmdi under wind and earthquakes

The objective of this article is to investigate vibration mitigation technique of a reinforced concrete (RC) building subjected to wind or earthquake ground motion. Numerical analysis of a RC building controlled by inerter tuned mass damper (TMDi) is conducted under independent action of wind forces and earthquake ground motion. The performance of the control devices is evaluated in terms of reduction in response parameters such as floor acceleration and displacements. The results show that vibration mitigation achieved from the TMDi system employed in the RC building varies significantly with the type of excitation. Nevertheless, the TMDi system is found to be more reliable than a TMD system.
