Response Prediction of VFPI Through Equivalent Long Period Wavelet of Near-Fault Ground Motion
Electronic Journal of Structural Engineering, 2022 Past research has revealed that a Variable Frequency Pendulum Isolator (VFPI) effectively controls the structural responses such as base shear and structural acceleration under far and near fault earthquakes and the VFPI may show excessive sliding ...

Combination of Spectral Representation and Wavelet Packets for Generating Long-Period Ground Motions
Advances in Civil Engineering, 2020 Far-field long-period ground motions (hereafter long-period ground motions) featuring low-frequency components are responsible for the resonant responses of high-rise buildings. In this context, it is beneficial to assess the dynamic performance of these
