Semi active tuned mass dampers of buildings: A simple control option

Demetriou, D., Nikitas, N. & Tsavdaridis, K. D. ORCID: 0000-0001-8349-3979 (2015). Semi active tuned mass dampers of buildings: A simple control option. American Journal of Engineering and Applied Sciences, 8(4), pp. 620-632. doi: 10.3844/ajeassp.2015.620.632


The present study investigates the effectiveness of a Proportional- Integral-Derivative (PID) controlled Variable Damping Semi-Active Tuned Mass Damper (VD-STMD) on reducing the vibration response of an earthquake excited multi-storey structure. The effectiveness of the controlled system is evaluated by comparing the structure’s overall dynamic behavior against that of an equivalent similar structure equipped with a conventional optimally designed passive Tuned Mass Damper (TMD). The numerical simulations show that the structure equipped with the PID controlled VD-STMD has improved vibration attenuation metrics when compared to the one equipped with the optimal TMD. From the numerical simulations, it was also evident that when material degradation and structural damage is considered, the TMD becomes instantly de-tuned resulting in reduced vibration mitigation performance. On the contrary, the VD-STMD controlled system remains insensitive to the stiffness parametric variation, suggesting the suitability of such systems in structural applications sustaining damage or in general change.
