Analytical Floor Response Spectra for Performance‐Based Seismic Design of Non‐structural Elements in Reinforced Concrete Frame Buildings

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Damage to non‐structural elements significantly impacts the seismic performance of buildings in terms of economic and functionality losses. Consequently, performance‐based seismic design of non‐structural elements has become a key pillar of a comprehensive building‐seismic resilience strategy, for instance, through loss‐targeted earthquake ...

Stability analysis of abstract systems of Timoshenko type [PDF]

Journal of Evolution Equations, 2016
We consider an abstract system of Timoshenko type $$ \begin{cases} _1{\ddot } + a A^{\frac12}(A^{\frac12} + ) =0\\ _2{\ddot } + b A + a (A^{\frac12} + ) - A^ = 0\\ _3{\dot } + c A + A^ {\dot } =0 \end{cases} $$ where the operator $A$ is strictly positive selfadjoint.

Experimental Modal Analysis‐Driven Gaussian Process Regression Modeling of Rectangular Steel Beams With Various Hole Geometries

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Understanding the dynamic behavior of structural components is crucial for optimizing performance and ensuring structural integrity. This study presents a new method that combines a systematic experimental investigation of four distinct hole geometries (circular, square, compact rectangular, and long rectangular) with varying hole counts, all ...

Drivers of human attitudes towards wolves Canis lupus in Kazakhstan

People and Nature, EarlyView.
Abstract Kazakhstan is recognized as a key stronghold for the grey wolf (Canis lupus). Nonetheless, the wolf status and the dynamics of human‐wolf coexistence in the region remain poorly understood. This study aims to fill that gap by exploring current attitudes towards wolves in Kazakhstan and identify the underlying drivers of these attitudes.

An efficient semi‐analytical approach for the free vibration behavior of DWCNTs on elastic foundations based on nonlocal elasticity theory

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 3, March 2026.
Abstract In this study, a comprehensive analytical framework is developed to investigate the free vibration behavior of double‐walled carbon nanotubes (DWCNTs) resting on an elastic foundation, based on Eringen's nonlocal elasticity theory. The DWCNTs are modeled as two coupled Euler–Bernoulli (EB) beams, explicitly incorporating intertube van der ...

Selectivity and Active State Formation During Pulsed CO2 Electroreduction in Cation‐Modified Electrolyte

ChemElectroChem, Volume 13, Issue 3, 3 February 2026.
In pulsed CO2 electroreduction, the electrolyte cation identity and size determine the multicarbon product formation over oxide‐derived Cu nanocatalysts. In situ X‐ray studies revealed enhanced dissolution and increased Cu lattice parameter adaptation linked to enhanced ethanol and suppressed hydrogen formation, suggesting an increased dynamicity of ...

Anisotropic Shear Properties of Organic Interfaces in Bio‐composite Materials

Advanced Functional Materials, Volume 36, Issue 12, 9 February 2026.
A novel cantilever design enables direct probing of shear properties at single organic interfaces within biocomposite prismatic ultrastructures. By decoupling lateral and torsional shear responses, the method reveals isotropic behavior in Atrina vexillum and pronounced anisotropy in Unio pictorum.

A Versatile Three Dimensional Traction Force Microscopy Framework for Uncovering the Mechanics of Bio‐Adhesion

Advanced Science, Volume 13, Issue 10, 18 February 2026.
This study introduces a versatile platform for quantifying three dimensional traction forces at bio‐adhesive interfaces. Integrating in situ stereo‐digital image correlation with finite element simulations allows for precise measurement of microscale displacements and traction forces in both dry and wet conditions.
