Direct Strut-and-Tie Model for Prestressed Deep Beams
Journal of Structural Engineering, 2001The 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, 2013By 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, 1990Truss 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, 2023The 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, 2001Strut-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

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, 2012B-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 ...

Design of Pile Caps With Strut-and-Tie Models
"SP-209: ACI Fifth Int Conf Innovations in Design with Emphasis on Seismic, Wind and Environmental Loading, Quality Con", 2002The present ACI Building Code (ACI 318-99) procedure for shear design of pile caps is the same approach used for 2-way slabs. The procedure involves determining a section thickness such that the concrete shear stress is greater than the applied shear stress on the critical section.
