Strength of Concrete Struts in Three-Dimensional Strut-Tie Models

Journal of Structural Engineering, 2016
AbstractThe design of structural concrete using strut-tie models requires establishing the effective strength of concrete struts, ensuring sufficient anchorage of reinforcing bars in nodal zones, and the geometric compatibility of the strut-tie model within the member geometry.

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.

Computer Graphics in Detailing Strut‐Tie Models

Journal of Computing in Civil Engineering, 1992
The paper describes the computer graphics program STAT, to aid the engineer in the detailing of concrete members using a rational design method that provides a clear understanding of the behavior of concrete structures and which is particularly useful in complex design situations. STAT is a special purpose computer graphic program designed for use with

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 ...

Density-Based Optimization for Strut-Tie Modeling

2018 4th International Conference on Green Technology and Sustainable Development (GTSD), 2018
Strut-and-tie modeling is an effective design method to deal with D-regions of reinforced concrete structures. This paper presents a topology optimization technique with the density filtering algorithm for automatically producing optimal strut-and-tie models. The algorithm utilizes the finite element method as a modeling and analytical tool.
