Automatic generation of planar RC Strut-and-Tie models [PDF]
This paper presents a proposal for determining Strut-and-Tie models of reinforced concrete plane elements. For the purposes of analysis, a computer program was developed and a discrete topological optimization was applied, using a truss member for the

Probabilistic assessment of load-bearing capacity of deep beams designed by strut-and-tie method [PDF]
This paper presents probabilistic assessment of load-bearing capacity and reliability for different STM of deep beams. Six deep beams having different reinforcement arrangement obtained on the basis of STM but the same overall geometry and loading ...

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

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

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

Assessment of deep beams with inadequate web reinforcement using strut-and-tie models
The objective of the study summarized in this paper was to evaluate the strut-and-tie design provisions of the 2017 AASHTO LRFD Bridge Design Specifications as a capacity assessment tool for structures with non-code-compliant crack control reinforcement ...
