Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin

Geological Journal, EarlyView.
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.

Seismic Fragility Analysis of Pile-Supported Wharves Subjected to Bi-Directional Ground Motions

Buildings
The purpose of this study is to determine the effect of the angle of seismic incidence on the fragility of regular pile-supported wharves. The investigation is performed by selecting the displacement demand at the deck level of critical piles located at ...

Refinement of the Quaternary seismic stratigraphy and analysis of buried glacial channels on the Labrador Shelf

Journal of Quaternary Science, EarlyView.
ABSTRACT The Laurentide Ice Sheet covered vast areas of North America during the Wisconsinan, including the Labrador Shelf, off the coast of eastern Canada. The shelf is characterized by glacial cross‐shelf troughs, which have been considered as predominantly eroded by the last ice advance.

Response Analysis of an RC Cooling Tower Under Seismic and Windstorm Effects

Acta Polytechnica, 2006
The paper compares the RC structure of a cooling tower unit under seismic loads and under strong wind loads. The calculated values of the envelopes of the displacements and the internal forces due to seismic loading states are compared with the envelopes

A novel approach for in situ benthic habitat characterization

Limnology and Oceanography: Methods, EarlyView.
Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Detecting Loosening of Bolt‐Flanged Pipe Using Smoothed Pseudo Wigner–Ville Distribution: Digital Twin‐Based Approach Using Convolution Neural Networks

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this paper, an integrated digital twin‐based fault‐diagnosis framework is proposed to detect bolt loosening in flanged pipe connections. The approach combines finite element‐based numerical modeling, experimental modal analysis, and advanced signal processing‐assisted deep learning to achieve reliable loosening detection under operational ...

Seismic hydrodynamic load analysis [PDF]

, 2017
Zangar's method for computation of seismic hydrodynamic loads acting at the inclined contour of a concrete gravity dam, has been reconsidered. Several numerical models are compared with the procedure recommended by Zangar, and a new regression formula is proposed, that eliminates the observed discrepancies.

Effects of Ambient Moisture and Large‐Strain Dynamic Preloading on the Dynamic Properties of the EAC‐1A Regolith Simulant

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The EAC‐1A lunar mare simulant, a silty sand, was selected by the European Astronaut Center (EAC) for use in the LUNA analogue facility's lunar simulation testbed. Its stress‐ and strain‐dependent shear modulus and damping ratio were determined via resonant column testing on specimens prepared either from ambient moisture material or oven ...
