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.

Sensitivity study on accuracy and relevant parameters in numerical modeling of internal tendon breaks

Structural Concrete, EarlyView.
Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

Exploring the potential of Textile Reinforced Concrete for corrosion‐insensitive retaining walls

Structural Concrete, EarlyView.
Abstract In a context where durability concerns, particularly the corrosion of steel reinforcement, remain a critical challenge for conventional reinforced concrete structures under severe exposure, Textile Reinforced Concrete (TRC) is emerging as a promising alternative.

Elastic local buckling of trapezoidal plates under linear stress gradients

Magazine of Civil Engineering
Steel plates play a pivotal role in the construction of different types of structures used in civil engineering. According to Eurocode 3, plated structures may be designed using three different approaches: the effective width method, the reduced stress ...

SERVICEABILITY BEHAVIOR OF NORMAL AND HIGH-STRENGTH REINFORCED CONCRETE T-BEAMS [PDF]

European Journal of Materials Science and Engineering, 2017
Serviceability behavior of Normal Strength Concrete (NSC) and High Strength Concrete (HSC) T-beams was experimentally evaluated. The crack pattern was observed, the effect of flange dimensions (breadth and thickness) on the crack pattern and load ...

Testing and modeling reinforced 3D concrete printing

Structural Concrete, EarlyView.
Abstract 3D Concrete Printing (3DCP) provides several advantages, including construction productivity and sustainability, although the presence of cold joints reduces structural performance, particularly in zones subjected to tensile stresses. In addition, it is difficult to reinforce 3DCP structures with conventional steel rebars, generally used to ...

The prototype DynamiX camera system – a high‐frame‐rate high‐dynamic‐range hard X‐ray integrating detector for fourth‐generation synchrotrons

Journal of Synchrotron Radiation, EarlyView.
This paper presents the first results from the DynamiX X‐ray imaging detector developed by the UK's Science and Technology Facilities Council for a new generation of photon light sources. Operating at a continuous frame rate of 534 kHz and with a per‐pixel per‐frame dynamic range of roughly five orders of magnitude, this work is the first step in ...

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

Insect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

AI‐Assisted Morphometric Analysis and Molecular Phylogeny for a Dactylogyrid (Monopisthocotyla) Skin Parasite of an Ornamental Crenuchid Fish From Brazil

Acta Zoologica, EarlyView.
ABSTRACT This study presents a formal description and taxonomic appraisal of Cacatuocotyle adrianoi sp. n., a Neotropical parasite belonging to the family Dactylogyridae, integrating AI‐assisted morphometric analyses, molecular data, and phylogenetic reconstruction. Phylogenetic analyses recovered Cacatuocotyle adrianoi sp. n.
