Reliability analysis of strut-and-tie models for the design of deep beams according to NBR 6118 (2023) [PDF]

Revista IBRACON de Estruturas e Materiais
The strut-and-tie method (STM) applied in the structural design of deep beams is a semi-probabilistic method, that does not take directly into account both the uncertainties associated with the variables involved and those inherent in the calculation ...

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

Experimental Testing and Strut-and-Tie Modeling of Full-Scale Precast Concrete Girders with FRP Repaired End Regions

Applied Sciences, 2020
Bridges located in cold regions are susceptible to extreme deterioration due to harsh climate conditions. Distressing of girder’s end regions is among the most common damage types in these bridges.

Verification of the bursting and spalling formulas in the FIB model code by finite element analyses of anchorage zones of pretensioned girders [PDF]

, 2016
In order to predict the stress and possible crack distribution in the anchorage zones of pretensioned girders several models have been developed as can be found in the fib Model Code, the ASHTOO code or Eurocode 2.

Strut-and-Tie Modeling of Reinforced Concrete Deep Beams [PDF]

Journal of Structural Engineering, 2018
Strut-and-tie models (STMs) are often used for the design of shear critical deep members because they can rationalize the shear transfer within discontinuous or disturbed regions in reinforced concrete structural elements. Most current codes of practice adopt the strut-and-tie method but provide very little guidance on how to select appropriate strut ...

Shear capacity of reinforced concrete corbels using mechanism analysis [PDF]

, 2012
A mechanism analysis is developed to predict the shear capacity of reinforced concrete corbels. Based on shear failure observed in experimental tests, kinematically admissible failure mechanisms are idealised as an assemblage of two rigid blocks ...

Numerical analysis of reinforced concrete dapped-end beams [PDF]

Revista IBRACON de Estruturas e Materiais
The 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.

Analysis of nodal stress on reinforced concrete two-pile caps supported on steel piles

Revista IBRACON de Estruturas e Materiais, 2020
: Reinforced concrete pile caps may be designed trough plastic models (strut and tie model) or models based on bending theory. The formulae available for verifying the stress is based on caps supported on concrete piles, with few studies about the stress
