Acoustic Signal‐Based Deep Learning Approach and Device for Detecting Interfacial Voids in Steel–Concrete Composite Structures

open access: yesAdvances in Civil Engineering, Volume 2025, Issue 1, 2025.
The reliable synergy between steel and concrete is an important evaluation criterion for the safety and long‐term use of steel–concrete composite structures (SCCSs). However, it is still a great challenge to realize fast and automated interface void detection for composite structures such as towers.

Analysis of Soil-Structure Interaction Effects of NPP Structures on Nonhomogeneous Subsoil [PDF]

open access: yes, 2019
This paper describes the soil-structure interaction (SSI) effects to the Nuclear Power Plant (NPP) structure with reactor VVER-1200. The simplified 1D and numerical 3D FE models of the nonhomogeneous subsoil are investigated.

The Linked Complexity of Coseismic and Postseismic Faulting Revealed by Seismo‐Geodetic Dynamic Inversion of the 2004 Parkfield Earthquake

open access: yesJournal of Geophysical Research: Solid Earth, Volume 129, Issue 12, December 2024.
Abstract Several regularly recurring moderate‐size earthquakes motivated dense instrumentation of the Parkfield section of the San Andreas fault (SAF), providing an invaluable near‐fault observatory. We present a seismo‐geodetic dynamic inversion of the 2004 Parkfield earthquake, which illuminates the interlinked complexity of faulting across time ...

A probabilistic full waveform inversion of surface waves

open access: yesGeophysical Prospecting, Volume 72, Issue 9, Page 3448-3473, November 2024.
Abstract Over the past decades, surface wave methods have been routinely employed to retrieve the physical characteristics of the first tens of meters of the subsurface, particularly the shear wave velocity profiles. Traditional methods rely on the application of the multichannel analysis of surface waves to invert the fundamental and higher modes of ...
