Corbel strut and tie modeling – Experimental verification
Structures, 2020Abstract 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 model design provisions
PCI Journal, 2011The 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.

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.

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.

Compatibility Strut-and-Tie Modeling: Part II—Implementation
ACI Structural Journal, 2012This paper presents the implementation and computational validation of a compatibility-based strut-and-tie model (C-STM) presented in a companion paper intended for analyzing the nonlinear force-deformation behavior of disturbed regions and structural concrete deep beams.

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

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.

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 ...
