Modified Roof-Top Garden as a Tuned Mass Damper for Vibration Control of Building Structure Under Earthquake Excitation
Abstract
Tuned Mass Damper(TMD) is very popular to mitigate the vibration of the structure under any type of random loadings like as Wind or Earthquakes. This research work mainly focuses on to modify the roof- top garden as a passive vibration controlling devices (RTGD) using the same principle of TMD.One of the important features of TMD is using huge mass to create the inertial force against earthquake forces. This passive energy dissipation system is not neededany additional mass because the mass of roof garden used as a TMD mass which is come from the mass of soil and plants. The roof and roof-top garden have been isolated by springs which have been given the spring force and also installed a viscous damper to provide the damping force against earthquake forces. Partially saturated soil condition of roof top garden has been taken to avoid the detuning effect. The obtained structural response under different earthquakes proved that this system is one of most capable to mitigate the Earthquake vibration and can be easily used in practically for building thestructures.
