Experimental Evaluation of Prototype Seismic Retrofits for Precast Concrete Hollow‐Core Floors

Earthquake Spectra, Volume 42, Issue 1, February 2026.
Existing hollow‐core floors are vulnerable to nonductile failure and potential collapse under earthquake loading. This study presents the development and experimental evaluation of novel comprehensive seismic retrofits for hollow‐core floors. These retrofits include a strongback‐type retrofit that provides an alternative gravity load path through steel

Influence of Biological Pretreatment of Wooden Dowels on Strength of Rotary Welded Joints

BioResources, 2023
Welding wood achieves joints whose strength is comparable with the strength of glued joints. When welding, the top of the dowel is not welded because of the lack of melted lignin.

Studying the Impact of Soil Stabilization Techniques on Rigid Pavement Joints Across Various Axle Loads

مجلة النهرين للعلوم الهندسية
Rigid pavement slabs are erected on a prepared subgrade or foundation layer, providing a hard and continuous surface. Transverse joints made of dowel bars connect them, and longitudinal joints made of tie bars join them longitudinally.

Strip loading in reinforced concrete: Mechanical modeling and experimental validation

Structural Concrete, Volume 27, Issue 1, Page 163-192, February 2026.
Abstract Strip loading of reinforced concrete is a common problem in engineering practice. The concrete compressive strength at the load introduction can be several times higher than the uniaxial concrete compressive strength, which can be attributed to geometrical and passive confining stresses caused by load dispersion and reinforcement, respectively.

Experimental investigations and design of precast concrete‐filled steel corrugated sheet slender columns with intermediate connection

Structural Concrete, Volume 27, Issue 1, Page 193-210, February 2026.
Abstract Concrete‐filled steel corrugated sheet (CFSCS) offers confinement to the core concrete while the outer galvanized corrugated steel sheet (GCSS) offers excellent corrosion resistance. Application of precast multiple CFSCS columns connected through high‐performance concrete (HPC) in constructing a slender column offers ease of construction while

Entangled Multistable Origami with Reprogrammable Stiffness Amplification and Damping

Advanced Functional Materials, Volume 36, Issue 5, 15 January 2026.
This study introduces a class of origami‐inspired metamaterials that overcome the limitations of existing multistable metamaterials by eliminating the need for rigid lateral confinements. Panel entanglement, snap‐through interactions, and instabilities synergy enable them to achieve extensive shape‐shifting, enhanced stiffness, and remarkable energy ...
