Study on an Optimal Strut-And-Tie Model for Concrete Deep Beams
Applied Sciences, 2019 The optimal strut-and-tie models (STMs) of two typical irregular concrete deep beams were constructed using evolutionary structural optimization and compared with those of previous studies.

Structural Performance of RC Beams containing Tension-Only Nodes
International Journal of Concrete Structures and Materials, 2018 Strut and Tie (S&T) models are used for the design of what are known as “discontinuity regions” in reinforced concrete (RC) structures. Building codes such as ACI-318 and Eurocode 2 do not give information on the nodes that only connect ties in S&T ...

Shear Strength Prediction for SFRC Shear Wall with CFST Columns by Softened Strut and Tie Model
, 2020 The steel fiber reinforced concrete (SFRC) shear wall with concrete filled steel tube (CFST) columns is an innovative composite structure. In order to calculate the shear strength of SFRC shear wall with CFST columns, the softened strut and tie model ...

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 ...

A Three-Dimensional Strut-and-Tie Model for a Four-Pile Reinforced Concrete Cap
Journal of advanced concrete technology, 2019 Reinforced concrete pile caps have been traditionally designed with sectional methods in codes and specifications. Since the 1990s, the two-dimensional strut-and-tie model (2D STM) methods, introduced in codes and specifications (Ref.

Strut and tie modeling for RC short beams with corroded stirrups
Latin American Journal of Solids and StructuresCorrosion of steel reinforcement is one of the major problems that shorten the service life of reinforced concrete (RC) structures. Steel stirrups, due to their location as an outer reinforcement, are more susceptible to corrosion problems and damage ...

Application of strut-and-tie model on eccentric columns
Mechanics, 2011 The popular strut-and-tie model is currently de fined by EC2 as a standard tool for simple structures. This paper explores the possibility of application of the strut and-tie model on more complex structures, specifically on the eccentric columns. Comparison with full numerical simulation shows that the strut-and-tie model can correctly predict the ...

Modified Softened Strut and Tie Model for Concrete Deep Beams
Journal of Engineering and Sustainable Development, 2012 A modified softened strut-and-tie model (MSST) for determining the shear strength of reinforced concrete deep beams is proposed in this paper. It is a simplified analytical model and several improvements have been made.

Strut-and-Tie Models of Masonry Shear Walls
, 2018 This paper contains theoretical fundamentals of strut and tie models, used in unreinforced horizontal shear walls. Depending on support conditions and wall loading, we can distinguish models with discrete bars when point load is applied to the wall (type I model) or with continuous bars (type II model) when load is uniformly distributed at the wall ...
