Modified interactive strut-and-tie model for shear strength prediction of RC corbels

open access: yesEngineering and Applied Science Research, 2019
On the basis of the modified Kupfer and Gerstle’s biaxial failure criterion ofconcrete, amodified interactive strut-and-tie model (MISTM) to predict the nominal shear strength of RC corbels was derived and is proposed in this paper.

On the optimal strut-and-tie models and design approach for the cable-pylon anchorage zone

open access: yesJournal of Civil Engineering and Management, 2019
The cable-pylon anchorage zone is a typical D-region in a cable-stayed bridge, for which there has been no uniform simplified design method until now. In this paper, based on the extensive statistics of actual projects, topology optimization techniques ...

Experimental investigation of the strut efficiency factor of bottle-shaped struts on local models and reinforced concrete deep beams [PDF]

open access: yesRevista IBRACON de Estruturas e Materiais
The design of concrete structural elements with discontinuous stress distribution is often done using strut and tie models and involves the design and detailing of reinforcement, as well as verifying the strength of struts and nodal zones.

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

open access: yesRevista 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 ...

Investigation on shear behavior of reinforced concrete deep beams without shear reinforcement strengthened with fiber reinforced polymers

open access: yesCase Studies in Construction Materials, 2022
Shear failure is an undesirable type of failure in terms of structural safety. Particularly, reinforced concrete (RC) deep beams without shear reinforcement are vulnurable to shear failure. In order to improve the shear behavior of such beams, externally

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

open access: yesRevista 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 ...

10th East Asia-Pacific Conference on Structural Engineering and Construction: Materials, Experimentation, Maintenance and Rehabilitation (EASEC-10) [PDF]

open access: yes, 2006
This paper presents the performance-based optimization of strut-and-tie models in reinforced concrete beam-column connections. The performance-based optimization (PBO) technique is employed to investigate optimal strut-and-tie models in reinforced ...

The strut-and-tie models in reinforced concrete structures analysed by a numerical technique

open access: yesRevista IBRACON de Estruturas e Materiais
The 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.

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

open access: yesRevista 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.

Testing and modeling of deep beams strengthened with NSM-CFRP reinforcement around cutouts

open access: yesCase 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.
