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 MateriaisThe 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 ...

The strut-and-tie models in reinforced concrete structures analysed by a numerical technique
Revista IBRACON de Estruturas e MateriaisThe strut-and-tie models are appropriate to design and to detail certain types of structural elements in reinforced concrete and in regions of stress concentrations, called "D" regions.

Investigating strut and tie model in deep beams [PDF]
, 2021 The Strut-and-Tie model (STM) approach evolves as one of the most useful design methods for shear critical structures and for other disturbed regions in concrete structures. The model provides a rational approach by representing a complex structural member with an appropriate simplified truss model.

Numerical analysis of reinforced concrete dapped-end beams [PDF]
Revista IBRACON de Estruturas e MateriaisThe reinforced concrete dapped-ends present in beams, being regions of discontinuity, require non-trivial models for their analysis and design, such as the strut-and-tie model, the shear-friction model, and the finite element method.

Testing and modeling of deep beams strengthened with NSM-CFRP reinforcement around cutouts
Case Studies in Construction Materials, 2021 The behavior of reinforced concrete (RC) deep beams strengthened with near-surface-mounted carbon fiber-reinforced polymer (NSM-CFRP) reinforcement around cutouts is examined in this study.

Reinforced concrete corbels strengthened with external prestressing
Revista IBRACON de Estruturas e Materiais, 2019 Reinforced concrete structures may demand, throughout their lifetime, the increase of the capacity load due to eventual changes in the load configuration. In this context, corbels could be considered structural elements which present great challenges for

Design criteria for unified strut and tie models [PDF]
Progress in Structural Engineering and Materials, 2001 AbstractIn the past two decades, the concept of strut and tie models (STM) has been used as one of the most popular and rational approaches for the design of non‐flexural members of reinforced concrete structures. Design guidelines based mainly on technology from past decades are given in many national codes.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy
The Anatomical Record, EarlyView.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.

British Educational Research Journal, EarlyView.Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.
