Design of deep pile caps by strut-and-tie models

Revista IBRACON de Estruturas e Materiais, 2019
There are many methods for designing pile caps, but there is still no consensus on which one provides the best approach for the practical engineers. In Brazil, many structural designers use the classical Blévot method; however, the applicability of the ...

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

Journal 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 ...

Strut-and-tie models for linear and nonlinear behavior of concrete based on topological evolutionary structure optimization (ESO)

Revista IBRACON de Estruturas e Materiais, 2019
The search for representative resistant systems for a concrete structure requires deep knowledge about its mechanical behavior. Strut-and-tie models are classic analysis procedures to the design of reinforced concrete regions where there are stress ...

Application of strut-and-tie models for assessing RC half-joints not complying with current code specifications

Acta Polytechnica, 2022
The work described is concerned with an investigation of the effectiveness of the use of strut-and-tie models for the structural assessment of half joints. Such elements form a part of many existing bridges which, although not complying with current code

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

Engineering 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.

Design criteria for unified strut and tie models [PDF]

, 2001
In 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.

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

Revista 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]

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 ...

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

Revista 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.
