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 ...

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.

Multiple linear regression models for shear strength prediction and design of simplysupported deep beams subjected to symmetrical point loads

KKU Engineering Journal, 2015
Because of nonlinear strain distributions caused either by abrupt changes in geometry or in loading in deep beam, the approach for conventional beams is not applicable.

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.

Sustainable and Seismically Resilient Confined Masonry: Global Progress in Research and Design Practice

Earthquake Spectra, Volume 42, Issue 4, November 2026.
Modern confined masonry (CM) construction consists of masonry walls confined by reinforced concrete (RC) tie‐columns and tie‐beams. When built correctly, CM buildings have shown good performance in earthquake's shaking. Even though CM construction has been practised for almost a century in some Latin American countries, its use and standardisation are ...

Neointimal Hyperplasia and Restenosis: Epidemiology, Pathophysiology, Animal Models, Clinical Features, Diagnosis, and Management

MedComm, Volume 7, Issue 11, November 2026.
The overall graphical diagram to summarize the pathological characteristics, pathogenesis, clinical manifestation, preclinical animal models, diagnostic methods, and intervention strategies for neointimal hyperplasia. Neointimal hyperplasia results from excessive proliferation and intimal migration of vascular smooth muscle cells (VSMCs) in the ...

Effect of loading type in concrete deep beam with strut reinforcement

Open Engineering
This study examined eight specimens of two groups of deep beam (DB) with the same dimensions and reinforcement quantity, where the first group had four specimens tested under two-point loads and the second group had four specimens tested under one-point ...

Flashy Neighbours: Psilocladus mantilleri Zeballos, Nunes, Silveira & Rosa, sp. nov., the First Termitariophile Firefly Larva (Coleoptera: Lampyridae)

Austral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT Fireflies are semelparous beetles whose immature stages are largely unknown. The comparatively few larvae known span diverse ecological niches, such as ground‐dwellers, aquatic (freshwater or marine), semi‐aquatic and arboreal. Psilocladus costae Vaz, Silveira & Rosa, 2020—a bromeliad dweller—is the only species of its genus and subfamily in ...

Utilizing the Strut-and-Tie Model for the Design and Analysis of Deep Beams

Modelling in Civil Environmental Engineering
Reinforced concrete deep beams, distinguished by a low shear span-to-depth ratio, exhibit complex, nonlinear strain distributions that render conventional beam theory inadequate.

Analysis of the structural behavior of beam-column joints in reinforced concrete frames considering bending towards the reduced side of the cross section [PDF]

Revista IBRACON de Estruturas e Materiais
The beam-column joints are called discontinuous regions and, therefore, could be designed by the strut and tie method. In beam-column joints where the bending plane coincides with the column's smaller dimension, the bending moments associated with the ...
