Bridging Dimensions in STEAM Education: Linking 2D Function Art and 3D Modeling Using GeoGebra

School Science and Mathematics, EarlyView.
ABSTRACT This study examines a constructionist‐oriented STEAM learning activity in which Grade 11 students used GeoGebra 3D to model bridges. Building on prior work in function art, the project extended mathematical art‐making from two‐dimensional representations to three‐dimensional structures, emphasizing the use of functions, geometric ...

Finite Element Modelling of Catenary Action in a Cross-Laminated Timber Floor System

, 2021
Buildings taller than four storeys require the designer to mitigate consequences of unexpected events, e.g. terrorism or accidents, such that a disproportionate collapse can be avoided after initial damage. One approach to halt damage propagation is using structural robustness, i.e. by providing alternative load paths. For platform-type cross-laminated

Capability and Limitations of a Tuned Mass Damper for a 15‐MW Semisubmersible Floating Wind Turbine

Wind Energy, Volume 29, Issue 11, November 2026.
ABSTRACT Large floating offshore wind turbines (FOWTs) under coupled aerodynamic and hydrodynamic loading exhibit broadband low‐frequency response in addition to the platform‐pitch resonance. Tuned mass dampers (TMDs) have been studied for a range of applications, but their net benefit under fully coupled operational conditions has not been quantified.

A Simplified Theoretical Model for Progressive Collapse Resistance of Steel Girders: Focusing on Load–Displacement Behavior Under Three Concentrated Loads

Buildings
Progressive collapse is characterized by disproportionate structural failure triggered by localized damage, such as column loss under extreme loading conditions.

Fire resistance of trapezoidal sheeting connected to a concrete beam

ce/papers, Volume 9, Issue 2-3, Page 2479-2482, September 2026.
Abstract Cold‐formed steel trapezoidal sheeting bending resistance degrades significantly in fire due to the small thickness of the profiles. The response can subsequently transition to catenary action, which develops only with sufficient restraint from fasteners. Fasteners therefore often govern the fire performance. In the presented study, connection

Mechanical Response and Dissipation of Progressively Fractured Annealed Laminated Glass Elements Under Large Cyclic Displacements

Engineering Reports, Volume 8, Issue 9, September 2026.
This article investigates the post‐fracture bending response of 2‐ply laminated (LG) samples composed of annealed (AN) glass and bonded by EVA or SG interlayers. Attention is given to the effect of partial and total glass fracture, and to the cyclic response of fractured LG specimens under large displacements.

Concept, Tests, and Optimum Design of Novel Negative Stiffness Friction Dampers for Seismic Protection of Long‐Span Bridges

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2719-2741, September 2026.
ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a
