Covariance Structure Modeling of Engineering Demand Parameters in Cloud‐Based Seismic Analysis

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 7, Page 1533-1551, June 2026.
ABSTRACT Probabilistic seismic demand modeling aims to estimate structural demand as a function of ground motion intensity—a critical stage in seismic risk assessment. Although many models exist to describe the structural demand, few consider the covariance among engineering demand parameters, potentially overlooking a key factor in improving the ...

The Use of FN‐Silk Networks as Extracellular Matrix‐Mimicking Support for 3D In Vitro Breast Cancer Models Improved the Model's Reproducibility in Drug Sensitivity

MedComm – Biomaterials and Applications, Volume 5, Issue 2, June 2026.
Chemotherapy treatment experiments were conducted on three breast cancer cell lines cultured in 2D, spheroids, and the novel 3D support: FN‐silk networks. The breast cancer cells cultured in FN‐silk networks were generally less sensitive to the drugs tested, compared to 2D cultures, potentially giving higher clinical relevance.

Behavior of Long‐Slotted Perforated Steel Plate Fuses in Timber Brace End Connections

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1247-1269, May 2026.
ABSTRACT Steel perforated plate fuses have emerged as a promising solution for mass timber seismic force‐resisting systems, offering tunable energy dissipation mechanisms, such as flexural and shear yielding, through geometric adjustments. This study examines the cyclic performance of perforated steel plate fuses employed in timber braced frames, with ...

Numerical Simulation of Post‐Yield Hysteretic Behavior of Lap‐Spliced Reinforced Concrete Bridge Pier Walls Under Earthquake Loading

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1356-1376, May 2026.
ABSTRACT Reinforced concrete pier walls designed before the 1970s often incorporate lap splice in potential plastic‐hinge regions. Previous experimental tests indicate that most of pier walls experienced post‐yield lap splice failure, necessitating a modeling approach that captures not only lap splice strength but also deformation capacity.

Seismic Fragility Analysis of Containment Structures in Nuclear Power Plants Considering Alkali‐Silica Reaction

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1467-1487, May 2026.
ABSTRACT This study quantifies the influence of alkali‐silica reaction (ASR) on the seismic fragility of prestressed concrete containment structures in nuclear power plants (NPPs). Global collapse was considered as the governing failure mode to maintain consistency with current risk assessment frameworks, and was captured using a finite element model ...

Evaluation of the accuracy of traditional Pushover methods in regular RC structures [PDF]

مدل‌سازی پیشرفته در مهندسی عمران
In the traditional pushover method, which has been the noticed by seismic design code, only the effect of the first vibration mode of the structure is considered, reducing the accuracy of the results, especially in mid-rise and high-rise structures.
