Anchorage System Contribution to Post‐Tensioned Bridge Collapse

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of

Programmable‐Stiffness Tensegrity Continuum Robot for Adaptive Multicurvature On‐Orbit Assembly

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 4, April 2026.
A bioinspired tensegrity‐based continuum robot (BTCR) with programmable stiffness enables adaptive multicurvature morphing via coordinated intra‐ and intermodule regulation. A unified energy‐based framework predicts self‐equilibrium and deformation for serial modules. Experiments and Simulations demonstrate reconfiguration into hexagonal, circular, and

STRUCTURAL BEHAVIOUR OF LAMINATED GLASS BEAMS: STANDARD VS PRESTRESSED

open access: yesce/papers, Volume 9, Issue 1, Page 161-170, April 2026.
Abstract This paper presents an integrated experimental and numerical study of laminated glass beams reinforced with prestressed steel cables. The aim is to evaluate how prestressing modifies the brittle behavior of glass, improving load‐bearing capacity and residual performance after fracture.

Large‐Area Metallic Nanohelices for Engineering Optical Chirality

open access: yesSmall, Volume 22, Issue 13, 3 March 2026.
By exploiting the nanoscale engineering of residual stresses in metallic thin films, this method enables scalable fabrication of submicrometer metallic helices with tunable geometry and material versatility. The resulting structures exhibit pronounced chiroptical responses across the mid‐ to near‐infrared range, offering a robust platform for chiral ...
