Strategy for eliminating high-frequency instability caused by multi-transmitting boundary in numerical simulation of seismic site effect

Frontiers in Earth Science, 2022
A multi-transmitting boundary is a local artificial boundary widely used for numerically simulating seismic site effects. However, similar to other artificial boundaries, the multi-transmitting boundary has instability issue in numerical simulation ...

Determination of Site amplification in the Campania-Lucania Region (southern Italy) by comparison of different Site-Response Estimation Techniques [PDF]

, 2008
We have applied a non-linear inversion technique to estimate both the earthquake source parameters and site response from a set of microearthquake records acquired by a dense seismic network, in order to provide a simple uniform site classification for ...

Effect of Soil Anisotropy on Ground Motion Characteristics

Buildings, 2023
Soil transverse isotropy results in different stiffness characteristics in horizontal and vertical directions. However, the effect is usually neglected in seismic motion analysis. In this study, an equivalent linear anisotropic soil model was established

Analysis of the Influence of Structure–Soil–Structure Interaction on the Seismic Response for Nuclear Power Plant ASTS

Energies, 2022
After the Fukushima nuclear accident in Japan, whether the structural safety of the nuclear power plant (NPP) can be guaranteed under an earthquake has been of wide concern. Automatic seismic trip systems (ASTS) have been deployed in NPPs.

Estimation of gas hydrate concentration from multi-component seismic data at sites on the continental margins of NW Svalbard and the Storegga region of Norway [PDF]

, 2008
High-resolution seismic experiments, employing arrays of closely spaced, four-component ocean-bottom seismic recorders, were conducted at a site off western Svalbard and a site on the northern margin of the Storegga slide, off Norway to investigate how ...
