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.

Aug 8, 2020 · ACI gives you two methods for determining whether ties are required: a) An evaluation of the compressive strain expected in the rebar. b) Whether the amount of …

ACI Committee 318 updated the Code provisions for shear capacity to reflect research findings on the effects of flexural reinforcement and section depth, using test data compiled and analyzed …

May 1, 2007 · There are additional shear ties at 24 inches on center each way with 180 degree hooks on top and 90 degree hooks on the bottom tying the two mats together. Can the shear …

The Finite Element Methods (FEM) and the Strut-and-Tie Model (STM) are the two primary methods defined in the ACI 318 standard for deep beam analysis. The transfer girder shown in …

The shear strength of deep beams is predominantly controlled by the effect of shear stress. These beams have a small shear span/depth ratio, a/d and are not part of the scope of this work. ACI …

Shear is the term assigned to forces that act perpendicular to the longitudinal axis of structural elements. Shear forces on beams are largest at the supports, and the shear force at any …

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 …

Finally, different aspects of reinforced concrete beam detailing based on ACI Code is explained in the following sections. Stirrups with different spacing-tackle vertical and diagonal shear. The …

ACI 318-08 and AASHTO LRFD specifications adopted strut-and-tie modeling in 2002 and 1994, respectively, for the design of deep beams or other regions of discontinuity.
