Overview of long-period ground motion professional works in Japan [PDF]

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

Effect of spatial variability in soft soil layers on long-period ground motion amplification [PDF]

E3S Web of Conferences
The Bangkok Basin is characterised by deep alluvial deposits predominantly composed of soft soils, which are highly susceptible to ground shaking induced by distant earthquakes.

Finite Difference Method-Based Critical Ground Motion and Robustness Evaluation for Long-Period Building Structures Under Uncertainty in Fault Rupture [PDF]

Frontiers in Built Environment, 2019
It is known that, while the stochastic Green's function method is suitable for generating ground motions with short periods, the three-dimensional finite difference method (FDM) is appropriate for ground motions with rather long periods.

Failure Probability and Economic Loss Assessment of a High-Rise Frame Structure under Synthetic Multi-Dimensional Long-Period Ground Motions

Buildings
Multiple research studies and seismic data analyses have shown that multi-directional long-period ground motion affects crucial and intricate large-scale structures like oil storage containers, long-span bridges, and high-rise buildings.

Time evolution of ground motion-dependent depolarisation at linear colliders [PDF]

, 2009
Future linear colliders plan to collide polarised beams and the planned physics reach requires knowledge of the state of polarisation as precisely as possible. The polarised beams can undergo depolarisation due to various mechanisms. In order to quantify

Ground-motion predictive equations for low-magnitude earthquakes in the Campania–Lucania area, Southern Italy [PDF]

, 2010
A key aspect of ground-shaking map calculation is represented by ground-motion predictive equations (GMPEs). In fact, ground-shaking maps obtained soon after an earthquake are calculated by integrating observed data and ground-motion estimates from GMPEs

Study on the shock-absorbing effect of a new staggered story isolated structure under the long-period earthquake motion

Frontiers in Earth Science, 2023
The finite element model of a new staggered story isolated structure is established. Using the time-history analysis method, the dynamic response state of the structure at each time step is calculated by integrating the acceleration time-history data ...

Quantification of rupture directivity effects on strong ground motion during the 8 January 2022 MS6.9 Menyuan earthquake in Qinghai, China

Frontiers in Earth Science, 2023
On 8 January 2022, an MS6.9 earthquake occurred in the Menyuan county, Qinghai province at the northeastern margin of the Tibetan Plateau. A dense observatory network consisting of accelerographs and intensity meters has obtained many acceleration ...

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 ...
