Combination of Spectral Representation and Wavelet Packets for Generating Long-Period Ground Motions [PDF]
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

Study on seismic isolation system for long-period ground motion
Nihon Kikai Gakkai ronbunshu, 2015 In this paper, the authors have developed a new type of horizontal seismic isolation system which has large effect of vibration isolation for ordinary earthquakes and suppresses the resonance of the isolation system due to long-period ground motions ...

Identification of Far-Field Long-Period Ground Motions Using Phase Derivatives [PDF]
Advances in Civil Engineering, 2019 The characteristics of long-period ground motions are of significant concern to engineering communities largely due to resonance-induced responses of long-period structures to far-field long-period ground motions which are excited by the existence of ...

Quantitative bounded method of special long-period ground motions
Magazine of Civil Engineering, 2022 The resonance effect of special long-period ground motions to (super) high-rise buildings is significant, which is likely to cause serious damage to these long-period structures. Therefore, the influence of long-period ground motions cannot be ignored in

Fatigue‐resistant Fe‐Mn‐Si‐based alloy seismic dampers to counteract long‐period ground motion
Japan Architectural Review, 2021 In recent years, resonance in high‐rise buildings due to long‐period ground motion, which induces large‐amplitude cyclic deformation of seismic dampers, has become a matter of significant concern.

Overview of long-period ground motion professional works in Japan
地震科学进展Long-period ground motion (LPGM) can result in prolonged vibration and even damage or collapse of structures and infrastructure with long natural vibration periods. With the emergence of flexible structures such as high-rise buildings and large oil tanks

Response analysis of long-period seismic action in far field to long-span continuous beam bridge with isolated high piers [PDF]
E3S Web of Conferences, 2021 In order to study the influence of far-field long-period seismic waves on high-pier and long-span continuous beam bridge, taking a high-pier and long-span continuous beam bridge with span arrangement of (95+170+95) m as an example, a numerical analysis ...

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 ...

Long-period ground motion effect in Shaanxi Province of Changning Ms6.0 earthquake [PDF]
E3S Web of Conferences, 2020 At 22:55 on June 17, 2019, an earthquake of magnitude 6.0 occurred in Shuanghe Town, Changning County, Yibin City, Sichuan Province. In Shaanxi Province, the obvious earthquake sense appeared in some places which are 600 km to 800 km away from the ...
