Multimethod Geophysical Imaging of Intermontane Basins: The Case Study of Cascina and Palarzano Plains (Central Apennines, Italy)

International Journal of Geophysics, Volume 2025, Issue 1, 2025.
A novel and integrated geophysical approach has been applied at Cascina and Palarzano plains (Abruzzi region, Central Apennines, Italy) to investigate their subsurface structure with particular attention to the faults bounding the basins. Both plains are characterized by the highest magnetic anomaly intensity measured over the Abruzzi region (up to 10 ...

Seismic Microzonation and Geotechnical Modeling Studies Considering Local Site Effects for İnegöl Plain (Bursa‐Turkey)

Earth and Space Science, Volume 11, Issue 11, November 2024.
Abstract Local site effects play a vital role in determining the level of structural damage to the structures built on soil. Therefore, correctly determining the underground layer structure and its physical characteristics in the lateral and vertical directions is essential for the geotechnical model.

Space–time finite element method with domain reduction techniques for dynamic soil–structure interaction problems

International Journal of Mechanical System Dynamics, Volume 4, Issue 2, Page 117-130, June 2024.
Abstract Design of earth structures, such as dams, tunnels, and embankments, against the vibrational loading caused by high‐speed trains, road traffic, underground explosions, and, more importantly, earthquake motion, demands solutions of the dynamic soil–structure Interaction (SSI) problem.

A comparison of ground motions predicted through one‐dimensional site response analyses and three‐dimensional wave propagation simulations at regional scales

Earthquake Spectra, Volume 40, Issue 2, Page 1215-1234, May 2024.
One‐dimensional (1D) site response analysis (SRA), which considers vertically propagating seismic waves from the bedrock to the surface, has been a common technique among geotechnical engineers to examine site‐specific ground shaking. However, observations from past earthquakes and analytical studies indicate that idealizations ingrained in 1D SRA may ...

State‐of‐the‐Art Seismic Studies of Loess Tunnels in China

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Large earthquakes occur frequently around the world. Due to the fragility of loess, the effects of seismic events on loess tunnel projects have received considerable in‐depth research attention. In this paper, we systematically review recent seismic research on loess tunnels and highlight deficiencies that require further study with a focus on the ...

Enhancing Seismic Performance: A Comprehensive Study on Masonry and Reinforced Concrete Structures Considering Soil Properties and Environmental Impact Assessment

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Approximately 20,000 people are killed annually on average by building and infrastructure collapses and failures caused by seismic activities. In earlier times, seismic design codes and specifications set minimal requirements for life safety performance levels. Earthquakes can be thought of as recurring events in seismically active areas, with severity
