Semi‐Active Movable Shear Keys for Seismic Response Control of Bridges

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 2, Page 483-499, February 2026.
ABSTRACT The size of the joint gaps plays a significant role in the dynamic performance of bridges. This has recently motivated the consideration of movable shear keys (MSKs), pioneered by the corresponding author, to enhance bridge performance by changing the bridge support/boundary conditions.

On soil-structure interaction in large non-slender partially buried structures [PDF]

, 2013
This paper addresses the seismic analysis of a deeply embedded non-slender structure hosting the pumping unit of a reservoir. The dynamic response in this type of problems is usually studied under the assumption of a perfectly rigid structure using a sub-

Predicting Seismic Debris Distributions of Collapsed Unreinforced Masonry Structures Through Physics Engines and Machine Learning Algorithms

Earthquake Spectra, Volume 42, Issue 1, February 2026.
Unreinforced masonry (URM) structures are widespread worldwide, particularly in older urban districts. However, URM buildings—particularly those constructed before the introduction of modern building codes—are highly vulnerable to seismic hazard, and prone to experiencing local and/or global failures when subjected to significant horizontal shaking ...

ТРАНСФОРМАЦИЯ РАСЧЕТНОЙ АКСЕЛЕРОГРАММЫ ПРИ УЧЕТЕ ВЗАИМОДЕЙСТВИЯ СИСТЕМЫ «СООРУЖЕНИЕ-ОСНОВАНИЕ» С УЧЕТОМ НЕЛИНЕЙНЫХ СВОЙСТВ ГРУНТОВ

Геология и геофизика Юга России, 2014
В данном исследовании определены ускорения фундаментной плиты, лежащей на нелинейно деформированном основании. Результаты показывают, что исходная акселерограмма претерпевает коррекцию, из чего следует вывод, что неучет изменения параметров внешнего ...

Modified Central Difference Method for Negative Stiffness SDoF System Under Ground Seismic Excitation

The Structural Design of Tall and Special Buildings, Volume 35, Issue 2, February 2026.
ABSTRACT The present paper deals with the analytical and numerical solution of the motion equation of a single degree of freedom (SDoF) oscillator with damping and negative stiffness (NS) due to seismic excitation at its base. The resulting solution shows that the structure's response displacement increases exponentially; thus, practically, there is no

Time History Analysis of a Steel Water Tank with Pinned and Fixed Foundations under Varying Ground Perturbations

Nigerian Journal of Technological Development, 2018
Earthquake is a natural phenomenon which is caused by sudden release of energy in the Earth's crust that creates seismic waves. Seismic response of an overhead water tank with varying foundation types subjected to five different earthquake accelerograms ...

A non-separable stochastic model for pulse-like ground motions [PDF]

, 2013
A phenomenological non-separable non-stationary stochastic model is proposed to represent near-fault pulse-like ground motions (PLGMs) by means of a parametrically defined evolutionary power spectrum (EPSD). Numerical data pertaining to ensembles of EPSD

Real-Time Estimation of Fault Rupture Extent Using Envelopes of Acceleration [PDF]

, 2008
We present a new strategy to estimate the geometry of a rupture on a finite fault in real time for earthquake early warning. We extend the work of Cua and Heaton who developed the virtual seismologist (VS) method (Cua, 2005), which is a Bayesian approach

Supershear Transitions and Bilateral Asymmetric Rupture of the 2025 Sagaing (Myanmar) Earthquake Revealed by Geodetic and Seismic Observations

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Sagaing Fault (SF) accommodates major plate motion in Myanmar, yet large earthquakes along it have rarely been captured by modern geodetic and seismic observations. The 2025 Sagaing earthquake generated an exceptionally long rupture (∼535 km), offering a rare opportunity to investigate rupture dynamics along continental transform fault. We

Response of Hollow Steel Structure Moment‐Resisting Frame Subjected to Post‐Earthquake Fire Loading

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study investigates the performance of a 10‐storey hollow steel moment‐resisting frame (MRF) under post‐earthquake fire (PEF) conditions using finite element modelling based on Eurocode provisions. Seismic response was modelled using a response spectrum analysis (peak ground acceleration [PGA] = 0.36 g), while fire was simulated via the ISO 834 ...
