Structural Performance of RC Beams containing Tension-Only Nodes

International Journal of Concrete Structures and Materials, 2018
Strut and Tie (S&T) models are used for the design of what are known as “discontinuity regions” in reinforced concrete (RC) structures. Building codes such as ACI-318 and Eurocode 2 do not give information on the nodes that only connect ties in S&T ...

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 15, Page 3796-3817, December 2026.
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Age and Growth Dynamics Suggest Biological Plasticity in Invasive Channel Catfish Ictalurus Punctatus Across Italian Rivers Systems

International Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT The North American channel catfish Ictalurus punctatus has successfully established populations across Europe; nevertheless, empirical data on its life‐history traits in this introduced area remain scarce. This study analyses age and growth of I. punctatus in the Po and Arno, two of Italy's principal river systems. Specimens of I.

Strut-and-tie models for deteriorated reinforced concrete half-joints [PDF]

, 2018
A reinforced concrete half-joint bridge consists of suspended span dapped-end beams or a full-width deck supported on the nibs of abutments or adjacent beams.

Revealing the Underlying Mechanisms in Performance Enhancement of Shellular Lattice Electrodes During Anion Exchange Membrane Water Electrolysis Process

Advanced Science, Volume 13, Issue 62, 9 November 2026.
Micro laser powder bed fusion enables architected nickel shellular lattice gas diffusion layers for anion exchange membrane water electrolysis. Among regular open cell geometries, the Gyroid lattice promotes bubble release, convective reactant replenishment and continuous electron transport, delivering low overpotentials, enhanced charge transfer and ...

Structural Design and Technology of Pocket Foundations for Long Precast Concrete Columns in Seismic Areas

Buildings
The connection between a prefabricated reinforced concrete column and a pocket foundation is a case treated from a general perspective in the European Standard named EN 1992-1-1 (EC2), and when the structural engineer deals with the dimensioning or ...

Study on an Optimal Strut-And-Tie Model for Concrete Deep Beams

Applied Sciences, 2019
The optimal strut-and-tie models (STMs) of two typical irregular concrete deep beams were constructed using evolutionary structural optimization and compared with those of previous studies.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, Volume 309, Issue 11, Page 3106-3122, November 2026.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Strut-and-Tie Models of Masonry Shear Walls

, 2018
This paper contains theoretical fundamentals of strut and tie models, used in unreinforced horizontal shear walls. Depending on support conditions and wall loading, we can distinguish models with discrete bars when point load is applied to the wall (type
