Numerical investigation of the cold-formed I-beams bending strength with different web shapes

Fracture and Structural Integrity, 2021
The wide use of cold-formed sections (CFS) in the field of steel constructions, favored by the multiple advantages they offer (lightness, ease of installation, etc.), has led us to reflect on a new process for manufacture of metal beams allowing the ...

Ferroelectricity and Ferroionic Dynamics in Two‐Dimensional CuInP2S6

Information &Functional Materials, EarlyView.
The coupled dynamics of ferroelectric polarization and Cu‐ion migration endow CuInP2S6 with unique ferroionic functionalities. This review connects structure, switching mechanisms, and device applications to provide a unified perspective on two‐dimensional ferroionic materials.

Characterization of Stress State of Corrugated Steel Web Girders Based on Mann-Kendall Criterion

Zhongwai Gonglu
To reasonably characterize the stress state of corrugated steel web girders and determine the failure load, the stress state evolution pattern of corrugated steel web girders was investigated in this paper based on the structural stress state theory ...

Second‐Life Thermoset Manufacturing via Mild Solvolysis of Epoxy‐Matrix Composites and Wet‐Laid Mat Production

Polymer Composites, EarlyView.
From end‐of‐life pultruded CFRP profiles (1) to second life composites (7) through mild solvolysis (2,3), wet‐laid nonwoven mat fabrication (4), resin impregnation (5), and compression molding (6). ABSTRACT The growing use of carbon fiber–reinforced thermosets has led to the accumulation of significant composite waste, posing environmental and economic

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

Structural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Shear capacity evaluation and buckling mechanisms of composite I-girders with corrugated steel webs

Case Studies in Construction Materials
Corrugated steel webs provide high shear stability, transverse rigidity, and construction efficiency, motivating the development of steel-concrete composite I-girders in which the web is connected only to a concrete slab at the top.

Pre‐failure behavior of continuous post‐tensioned and post‐grouted beam in case of tendon failure

Structural Concrete, EarlyView.
Abstract Grouted tendons are a common solution for long‐span bridge structures. The grout provides bond and corrosion protection for prestressing steel. However, if the grouting is defective, corrosion of the prestressing steel may initiate and eventually lead to tendon failure.

The effect of perforations on the deformability of welded beam with corrugated webs

Инженерно-строительный журнал, 2019
Perforating steel beams is inevitable in some cases such as setting the technical equipment, though it decreases the carrying capacity of the element. The lack of information about the nature of the work, the values of critical stresses, the stability of

VISUAL NEGOTIATIONS OF GENTRIFICATION IN TORONTO: Contestation, Politicization and Resistance through Urban Signage

International Journal of Urban and Regional Research, EarlyView.
Abstract This article engages signage as a medium through which urban stakeholders negotiate the politics of housing redevelopment and gentrification in cities. Focusing on Toronto, we examine housing‐related signage in three neighbourhoods where social mix approaches to redevelopment have ushered in gentrification: Parkdale, Regent Park, and Moss Park.
