Base Excitational Dynamic Behaviour of Frictional Pendulum Bearing on Multi-Storeyed Buildings

The main objective is to study nonlinear dynamic analysis of different 3D Friction Pendulum System (FPS) isolators and its behaviour during different earthquake motions. The analytical response of the model is studied for buildings with G + 4 storeys with and without Frictional Pendulum Systems using ANSYS Workbench 16.1 and the results are interpreted. The experimental results of the 1940 El Centro, 1995 Kobe, earthquakes show that the proposed isolators can reduce the undesirable seismic responses of the structure by lengthening the fundamental period of the structure during earthquakes, and the Friction Pendulum System (FPS) provides the structure with excellent isolation function under the far- and near- source excitations and strong ground motions with long predominant periods. From these observations, it can be concluded that the proposed FPS isolator is a powerful tool for enhancing the seismic-resistibility of structures.
