STEP is a tool developed to aid engineers with implementing the strut-and-tie method for the design of bridge substructure components. The engineer should be familiar with the limitations and the assumptions of the program prior to using it as a design tool.
In 2014, STM provisions were moved into the main body of the code as Chapter 23, Strut-and-Tie Method. This document focuses on the ACI 318-19 implementation of strut-and-tie modeling.
Strut and tie - Concrete Centre
Strut and tie modelling (STM) is a simple method which effectively expresses complex stress patterns as triangulated models. STM is based on truss analogy and can be applied to many elements of concrete structures.
How to construct a Strut-and-Tie model? 2.If a truss can be formulated, is it adequate or is there a better one? 3.If there are two or more trusses for the same structure, which one is better?

2006年12月19日 · Strut-and-Tie Model for Structural Concrete Design commonly idealize struts, however, other shapes are also possible. Should the compression stress be high in the strut, reinforcement may be necessary to prevent splitting caused by transverse tension (similar to the splitting crack that develops in a cylinder supported
Strut-and-tie model and its applications in reinforced concrete …
2023年12月1日 · Strut-and-tie model (STM), with its truss analogy, is yet a powerful tool for analyzing and designing complex prestressed and reinforced concrete structures. Which represents a simplistic method that predominantly provides conservative strength predictions.
Strut-and-tie modeling (STM) is a technique that is commonly used to reduce complex states of stress in reinforced and prestressed concrete structures into a simplified truss model. STMs are made up of elements loaded uniaxially in tension (referred to as ties) or compression (referred to as struts). The intersection points of the struts and ties
Advances and applications of the strut-and-tie method in …
2024年11月1日 · The Strut-and-Tie Method (STM) is a versatile and powerful approach widely used in the design and analysis of reinforced concrete structures, particularly in regions with complex stress distributions and discontinuities. This review article delves into the theoretical foundations, practical applications, and experimental validations of the STM.
2023年6月14日 · Strut-and-tie models (STMs) were first used at the end of the nine-teenth century as a concrete design method. The method was added to ACI 318 in 2002 as Appendix A. In 2014, STM provisions were moved into the main body of the code as Chapter 23, Strut-and-Tie Method. This document focuses on the ACI 318-19 implementation of strut-and-tie modeling.
