Survey on the Role of Beam-Column Connections in the Progressive Collapse Resistance of Steel Frame Buildings

open access: yesBuildings, 2023
The behavior of steel frame buildings under progressive collapse conditions depends on a combination of several parameters, including the interplay between different collapse resistance mechanisms that are mobilized in different structural components ...

Performance of bolted steel-beam to CFST-column joints using stiffened angles in column-removal scenario [PDF]

open access: yes, 2019
This paper presents three experimental investigations on the performance of steel-beam to CFST-column joints using stiffened angle, long bolts and fin plate under a middle column removal scenario. Three specimens were designed and tested.

Geometric Optimization and Mechanical Performance Enhancement of Auxetic Structures for High‐Impact Applications Through Fused Deposition Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the mechanical performance of three auxetic structures, identifying a re‐entrant‐star hybrid as the most effective for impact absorption. Finite element simulations and experiments demonstrate significant gains in energy absorption and flexural strength after geometric optimization. This study investigates the mechanical performance

Seismic Progressive Collapse: Qualitative Point of View

open access: yesCivil Engineering Dimension, 2009
Progressive collapse is a catastrophic structural phenomenon that can occur because of human-made and natural hazards. In progressive collapse mechanism, a single local failure may cause a significant deformation which then may lead to collapse of a ...

Parametric plastic collapse loads and their validation for horizontal saddle supported storage vessels [PDF]

open access: yes, 2003
In general, progressive plastic collapse occurs in vessels with low values of R/t ratio, typically less than 200, and elastic-plastic buckling is observed in vessels with higher R/t ratios. The aim of this paper is to examine various theoretical analyses

X‐Ray Tomography Analysis of Damage Mechanisms in Metal Matrix Syntactic Foams During Compression

open access: yesAdvanced Engineering Materials, EarlyView.
In situ synchrotron X‐ray tomography is used to investigate the internal damage mechanisms of AlSi12 metal matrix syntactic foam with ceramic hollow spheres during compressive loading. It is concluded that a homogeneous distribution of the second‐phase filler material results in a sequential collapse in a localized region; this leads to controlled and ...

Fabrication of Multifunctional FeSi Gyroid Lattice Composites via Additive Manufacturing and Polymer Infiltration

open access: yesAdvanced Engineering Materials, EarlyView.
A two‐step approach combining laser powder bed fusion of FeSi electrical steel with Bakelite infiltration enables the fabrication of multifunctional gyroid lattice composites. The resulting structures exhibit high strength, magnetic anisotropy, and complete polymer infiltration, demonstrating a simple and scalable route toward lightweight, mechanically
