Abstract
The Triple Friction Pendulum (TFP) bearing is highly adaptive in nature that contains three effective pendula with four spherical sliding surfaces. By considering desirable displacement capacity with effective damping and period, TFP systems are to be designed. A comparative response of the building isolated by the Single Friction Pendulum (FPS) and Triple Friction Pendulum (TFP) with same effective damping, effective time period, and displacement capacity under different hazard levels of earthquake along with its mathematical models. It shows that the performance of TFP is superior over the FPS. Owing to its multiple sliders, which dissipate seismic energy and distribute sliding displacement over the multiple surfaces. It is also found that the TFP bearing stiffens at low level of input, softens with increasing input, and then stiffens again at higher levels of input. Hence, it behaves adaptively in nature under different hazard levels of earthquake.
