Optimized Design of Anchor Plates for 2200 MPa-Class Prestressing Anchorage Zones
BuildingsThe strength of prestressed steel strands has developed towards high strength, increasing from 1860 MPa to over 2200 MPa. The stress in the prestressed anchorage zone is more concentrated and complex, and the anchor plates for dispersed loads need to be ...

Reliability analysis of strut-and-tie models for the design of deep beams according to NBR 6118 (2023) [PDF]
Revista IBRACON de Estruturas e MateriaisThe 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 ...

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 ...

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 Verification of Strut and Tie Model Design Method [PDF]
ACI Structural Journal, 2007 Although strut-and-tie models (STM) appear to provide safe, lower-bound designs for irregular concrete members, there have not been many experimental validations of them. This paper presents the result from two series of testing of STM specimens. In the first series, 6 specimens having different reinforcing designs but the same overall geometry and ...

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.

Analysis of conventionally reinforced coupling beams using non-linear strut-and-tie model
Proceedings of the Institution of Civil Engineers : Structures and buildings, 2020 The non-linear strut-and-tie model (STM) can be used to analyse and predict the behaviour of reinforced concrete in disturbed regions.

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.

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
