Learning Rocking Dynamics From Sparse Shake‐Table Data With Interpretable Physics‐Informed Neural Networks

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT We present a hybrid interpretable Physics‐Informed Neural Network Long‐Short Term Memory (Hybrid PINN LSTM) framework for predicting the seismic response of rocking blocks. Existing analytical models rely on uncertain idealizations, while purely data‐driven and machine‐learning approaches lack physical consistency and interpretability.

From a Probabilistic PBEE Framework to Risk‐Targeted Structural Design With Cascading Hazards: Engineering Application for Seismic–Radiological Safety

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Earthquake‐induced damage of structures can trigger cascading hazards, linking structural performance to nonstructural consequences. In current engineering practice, these two aspects are typically addressed separately, limiting the ability to account for such coupled effects in design.

Crustal structure of the eastern Piedmont and Atlantic coastal plain in North Carolina and Virginia, eastern North American margin

Earth, Planets and Space, 2019
The eastern North American rifted margin is a passive tectonic margin that has experienced Paleozoic ocean closure and Mesozoic continent rifting. To understand evolution of this continental margin, we modeled the two-dimensional P-wave and S-wave ...

Seabed topography beneath Larsen C Ice Shelf from seismic soundings [PDF]

The Cryosphere, 2014
Seismic reflection soundings of ice thickness and seabed depth were acquired on the Larsen C Ice Shelf in order to test a sub-ice shelf bathymetry model derived from the inversion of IceBridge gravity data.

Analytical Framework for System‐Level Fragility Surfaces of Reinforced Concrete Bridges Under Mainshock‐Aftershock Sequences

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Conventional single intensity measure (IM) fragility approaches with simplified component dependency assumptions overlook the progressive damage accumulation and evolving inter‐component correlations that govern system behavior under mainshock‐aftershock (MSAS) loading.

Energy‐Based Characterisation of Earthquake Damage in Masonry Infills Through Combined In‐Plane and Out‐of‐Plane Experimental Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The seismic capacity of structural systems/members is usually defined in terms of deformation thresholds. Although this is effective in many circumstances, disregarding cumulative quantities such as hysteretic energy may be ineffective when low‐cycle fatigue is relevant (e.g., long‐duration ground motions, very soft soils, ground‐motion ...

Design Internal Forces of Non‐Dissipative Members in CBFs With Regular and Irregular Brace Configurations

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Steel Concentrically Braced Frames (CBFs) are widely used in seismic regions, with chevron and split‐X configurations commonly adopted for their structural efficiency and architectural flexibility. Although extensive research has been carried out on these systems, the effectiveness of the formulations available in the literature for estimating

Crustal-Scale Duplexes Beneath the Eastern Rioni Foreland Basin in Western Georgia: A Case Study from Seismic Reflection Profile

Geosciences
Our understanding of foreland basin subsurface structures relies heavily on seismic reflection data. The seismic profile across the eastern Rioni foreland basin in western Georgia is critical for characterizing its deformation structural style.

Inference for stellar opacities from seismic studies of the hybrid β Cep/SPB pulsators

EPJ Web of Conferences, 2017
We present a comprehensive seismic study of the three pulsating stars of β Cep/SPB type: v Eridani, 12 Lacertae and γ Pegasi. Models with the modified mean opacity profile are constructed in order to account for both the observed frequency range and the ...
