The seismic safety of reinforced concrete (RC) buildings is at risk of being compromised due to the excessive lateral vibrations that may happen during earthquakes. The article presents the research which aims at finding out the effectiveness of Tuned Mass Dampers (TMDs) as the additional damping devices to lessen such reactions in a mid-rise RC structure. A model of a G + 5 building was designed in STAAD.Pro, and Response Spectrum Analysis (RSA) was done according to IS 1893:2016. Two models were used to analysis one depicting the bare structure and the other with a roof-mounted TMD tuned to the fundamental mode of vibration. The comparative analysis results of the experiments revealed that the TMD-controlled model was able to reduce roof displacement and inter-storey drift by about 25–30% and base shear to a moderate extent.

摘要

The seismic safety of reinforced concrete (RC) buildings is at risk of being compromised due to the excessive lateral vibrations that may happen during earthquakes. The article presents the research which aims at finding out the effectiveness of Tuned Mass Dampers (TMDs) as the additional damping devices to lessen such reactions in a mid-rise RC structure. A model of a G + 5 building was designed in STAAD.Pro, and Response Spectrum Analysis (RSA) was done according to IS 1893:2016. Two models were used to analysis one depicting the bare structure and the other with a roof-mounted TMD tuned to the fundamental mode of vibration. The comparative analysis results of the experiments revealed that the TMD-controlled model was able to reduce roof displacement and inter-storey drift by about 25–30% and base shear to a moderate extent. These results lead to the conclusion that if TMDs are correctly tuned, they can not only make a significant contribution to the seismic safety of RC buildings but also be economical. Our study can be extended to the exploration of Tuned Liquid Dampers (TLDs), hybrid TMD-TLD, and algorithmic optimization in designing the damper.
