Strut-and-tie model design provisions

PCI Journal, 2011
The overall objective of the research project summarized in this paper was to develop simple and safe design guidelines for deep beams. To accomplish the research objective and related tasks, a database of 868 deep-beam tests was assembled from previous research.

Corbel strut and tie modeling – Experimental verification

Structures, 2020
Abstract ACI 318-14 analyzes reinforced concrete corbel by shear friction (SF) and/or strut-and-tie modeling (STM). This work presents the results of experimental tests conducted on three reinforced concrete corbels that had a height of 390 mm and a width of 115 mm. The corbels had different shear span to effective depth ratios (a/d), which were 0.5,

Strut and Tie Models

SP-198: Structural Concrete - Behavior to Implementation, 2001
The evolution of strut and tie models is reviewed and their characteristics are discussed. From their evolution it is seen that more design effort should be expended on developing a reasonable truss than on refined calculations of nodal stresses and permissible concrete stresses. Strut and tie models are design tools.

Direct Strut-and-Tie Model for Prestressed Deep Beams

Journal of Structural Engineering, 2001
The strut-and-tie method is a promising analytical tool for the design of disturbed regions where the conventional plane bending theory does not hold. These include pile caps, corbels, frame joints, deep beams, and so forth. This paper focuses on the application of a strut-and-tie model to prestressed deep beams.

The Preliminary Calculation Process of Strut-and-Tie Model

Applied Mechanics and Materials, 2013
By briefly introducing the main steps of using strut-and-tie (STM) , this paper showing the preliminary calculation process. In this paper, defining D-region is the very first step in design.Then paper gives the method to calculate the reinforcement needed to meet required tie capacities.

Stress Fields for Nodes of Strut‐and‐Tie Models

Journal of Structural Engineering, 1990
Truss models have been developed and applied to the ultimate strength design and detailing of two‐dimensional reinforced concrete members loaded in their plane. Such a truss is composed of struts and ties which represent one‐dimensional stress fields. The nodes, however, form two‐dimensional stress fields whose bearing capacity also needs to be checked.

Strut-and-tie models obtained by way of topological optimisation

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2023
The strut-and-tie model is widely used for the analysis and design of reinforced concrete structures under a plane stress state. To apply this model, it is necessary to define strut-and-tie systems that represent the flow of stresses generated in the analysed structure. To make the concept of the model less dependent on designer experience for regions

Practical Design with Strut-and-Tie Models

Structures 2001, 2001
Strut-and-tie models are an especially valuable tool for designing discontinuity regions (D-regions) of structures with irregular geometry where the flow of forces is not well known, like at points where high forces are applied to a beam, for shear walls with openings or for connections of members. The latter is especially important for highly stressed

Modelling Structural Concrete with Strut-and-Tie Model Combined with 2D Finite Elements - A Model Factor for the Assessment of Strut-and-Tie Models

2017
Despite being a widely used structural material, the deep knowledge on behaviour of structural concrete represents a continuous challenge to the technical community. The definition of local and global interactions between materials, the accurate definition of its geometry, supports and loads are basic requirements to establish adequate models to ...

An Overview of Strut-and-Tie Model and its Common Challenges

International Journal of Engineering Research in Africa, 2012
B-Regions are parts of the structure in which Bernoulli's principle of straight-line strain is used. D-Regions are parts of the structure with a complicated variation in strain. In essence, D-Regions contain the parts of structure which are near to the concentrated forces or steep changes in geometry which are so-called geometrical discontinuities or ...
