Full-Scale Test on Hysteretic Behavior of T-Shaped Steel Beam–Column Joints with Locally Corrugated Web (RBS) Considering Folding Effect

Buildings
Steel frame structures have been increasingly widely used in high-rise and multi-story building design. However, traditional rigid welded beam–column joints exhibit poor ductility and high residual stress, which are key reasons for their susceptibility ...

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

Fracture and Structural Integrity, 2022
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 ...

NONLINEAR BEHAVIOR OF CANTILEVER GIRDERS WITH CORRUGATED STEEL WEBS [PDF]

JES. Journal of Engineering Sciences, 2008
The shear behavior of cantilever girders with corrugated steel webs has been investigated here experimentally and analytically. Three cantilever beams with corrugated steel webs were tested to failure under shear; the failure was due to buckling of the web.

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.

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.

Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

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.

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, Volume 55, Issue 4, Page 2201-2232, June 2026.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Wheat flour particle size: Influence of mill design and effects on quality and performance

JSFA reports, Volume 6, Issue 6, Page 202-211, June 2026.
Abstract Among the various characteristics of wheat (Triticum aestivum) flour, particle size is of paramount importance globally. The industrial process of separating the three main components (endosperm, bran, and germ) must ensure that the desired quality is delivered to customers through a progressive reduction in the size of the endosperm until the
