Hysteretic magnetic behavior of AuCo nanocomposite systems

open access: yes, 2018
Oggigiorno, la ricerca di sistemi nanocompositi costituiti da almeno due fasi magnetiche sta suscitando una sempre maggiore attenzione. In effetti, l’intima miscelazione di due o più fasi magnetiche a livello nanometrico può dare origine a materiali che mostrano proprietà uniche.

Seismic performance evaluation of a century‐old RC columns for railway's structural concrete

open access: yesStructural Concrete, EarlyView.
Abstract Since the Great Kanto Earthquake of 1923 in Japan, reinforced concrete (RC) has been adopted for railway bridge piers, and some of these structures, now over 100 years old, continue to support transportation in the capital city of Tokyo. Evaluating the seismic performance of these few remaining RC structures has become an urgent issue. Because

Bond‐slip modeling for reinforced concrete beam‐column joints with plain reinforcement bars: Insights from numerical validation

open access: yesStructural Concrete, EarlyView.
Abstract The previous seismic events indicated the vulnerability of old reinforced concrete (RC) structures against earthquakes due to the absence of seismic detailing and capacity design specifications in such buildings. In this context, beam‐column joints (BCJ) of the existing RC structures built before the 1970s have exhibited poor structural ...

Innovative development and structural behavior of hollow columns using inflatable molds

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces a novel approach for constructing hollow columns using precast (PC) methods enhanced by inflatable air tubes as internal molds. The proposed method addresses practical challenges in conventional hollow column construction, such as limited constructability, high production cost, and interference between internal molds and ...

Experimental analysis of bolted connections for precast concrete walls under cyclic tensile loading

open access: yesStructural Concrete, EarlyView.
Abstract Dry‐bolted connections in precast wall structures simplify the assembly process and offer significant advantages in terms of construction speed and cost. In fact, the reduction of the required workmanship, compared to wet connections, makes this solution highly competitive.

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

Impact of Seasonal Composition on the Long‐Term Performance of Post‐Consumer Recycled Polypropylene

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 15, April 15, 2026.
Ten batches of post‐consumer polypropylene recyclate were examined over a period of 15 months. Despite identical MFR and density specifications, there were significant differences in their composition, affecting mechanical performance. Elongation at break and crack resistance varied particularly strongly.
