Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Conditional Probabilistic Model for Normalized Hysteretic Energy Given Ductility Ratios

open access: yesBuildings
Hysteretic energy, a critical component of seismic input energy, is predominantly dissipated through the hysteretic behavior of structural members in most conventional structures.

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa

open access: yesStructural Concrete, EarlyView.
Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.

Sensitivity of 3D Base‐Isolated Buildings to Individual Isolator Variability

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2653-2668, September 2026.
ABSTRACT Variability in elastomeric isolators arises from differences in rubber formulation and curing, leading to noticeable changes in stiffness and damping among nominally identical bearings. While most previous studies have examined global isolator variability associated with environmental or aging effects, individual isolator variability has ...

Soil Dynamic Constitutive Model for Characterizing the Nonlinear-Hysteretic Response

open access: yesApplied Sciences, 2017
Characterization of nonlinear hysteretic responses plays a significant role in predicting soil behaviors. They are mostly described with either simple empirical functions or complex constitutive models.
