Parametric Study on Steel Girders with Corrugated Webs [PDF]

Port Said Engineering Research Journal, 2020
I-shaped Steel Girder with Corrugated Webs [SGCW] are used in steel structures because of their notable advantages. SGCW permit using a thin web plate without using stiffeners.

Beyond d‐Band Catalysis: A Critical Review and Descriptor Framework for Rare‐Earth Engineering in Lithium–Sulfur Batteries

Advanced Science, EarlyView.
Rare‐earth catalysts regulate lithium–sulfur battery chemistry through f‐orbital–mediated interactions, enabling simultaneous polysulfide adsorption and catalytic conversion on conductive carbon hosts. This synergistic control suppresses the shuttle effect, accelerates redox kinetics, and guides stable Li2S nucleation, providing a mechanistic framework

Numerical analysis of beam with sinusoidally corrugated webs [PDF]

AIP Conference Proceedings, 2018
The paper presents numerical tests results of the steel beam with sinusoidally corrugated web, which were performed in the Autodesk Algor Simulation Professional 2010. The analysis was preceded by laboratory tests including the beam’s work under the influence of the four point bending as well as the study of material characteristics.

Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Digital and Gender Attributes of IC in Sustainability Reporting of Italian Firms

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Italian listed enterprises increasingly rely on intellectual capital (IC) to enhance competitiveness and sustainability performance. As IC, comprising human, structural, and relational capital, is rarely recognised in financial statements due to the lack of standardised frameworks, its disclosure has gained relevance in sustainability ...

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.

A softened membrane model for single-box multi-cell composite box-girders with corrugated steel webs under pure torsion

Advances in Bridge Engineering, 2022
To analyze the nonlinear torsional behavior of single-box multi-cell prestressed concrete (PC) or reinforced concrete (RC) composite box-girders with corrugated steel webs (BGCSWs), a new theoretical model called unified softened membrane model for ...

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.
