Modified Softened Strut and Tie Model for Concrete Deep Beams

Journal of Engineering and Sustainable Development, 2012
A modified softened strut-and-tie model (MSST) for determining the shear strength of reinforced concrete deep beams is proposed in this paper. It is a simplified analytical model and several improvements have been made.

Strut and tie modeling for RC short beams with corroded stirrups

Latin American Journal of Solids and Structures
Corrosion of steel reinforcement is one of the major problems that shorten the service life of reinforced concrete (RC) structures. Steel stirrups, due to their location as an outer reinforcement, are more susceptible to corrosion problems and damage ...

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 ...

Experimental evaluation of optimized strut‐and‐tie models for a dapped beam

Structural Concrete, 2016
AbstractStrut‐and‐tie modelling constitutes a powerful tool for the design of complex structural reinforced concrete elements. It has been proved numerically that strut‐and‐tie (ST) models obtained using structural optimization methods produce designs that are more efficient.

Investigation of Load-Bearing Capacity for Reinforced Concrete Foundation Retrofitted Using Steel Strut–Tie Retrofit System

, 2023
To reduce the thickness of reinforced concrete foundation members used in construction and structural applications, a previous study developed and tested a strut–tie retrofit system installed in the foundations.

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.

Enhanced strut-and-tie model for reinforced concrete pile caps

, 2017
Strut-and-tie models provide a simple and rational way to design discontinuity regions in reinforced concrete structures. However, when it comes to three-dimensional concrete elements such as pile caps, enhancements are needed to ensure a reliable and ...

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.
