Introducing strut efficiency factor in the softened strut and tie model for the ultimate shear strength prediction of steel RC deep beams based on experimental study

European Journal of Environmental and Civil Engineering, 2021
In this paper, an empirical model for a strut efficiency factor is proposed and introduced in to the softened strut and tie model to predict the ultimate shear strength and the corresponding ultimate load of simply supported steel reinforced concrete (RC)

Investigation of the strut‐and‐tie model of a two‐plane cable‐stayed bridge tower under vertical component of the cable force

Structural Concrete, 2021
The geometry and mechanical behavior of concrete bridge towers are complex. Hence, it is important to generate a rational mechanical analysis model for structural design.

Strut‐and‐tie model for column‐to‐drilled shaft connections in reinforced concrete bridge columns subjected to lateral loads

Structural Concrete
Drilled shafts with a larger diameter than columns are frequently adopted as the foundation of highway bridge columns due to their superior economic efficiency and lower impact on existing facilities in the urban built‐up area.

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.

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.

Compatibility Strut-and-Tie Modeling: Part II—Implementation

ACI Structural Journal, 2012
This 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, 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

Enhancement of shear strength of deep beams using hybrid fibres and suggesting an alternative for strut and tie model

, 2020
This paper investigates the behaviour of 4 deep beams prepared by varying the percentages of horizontal and vertical shear reinforcement. First, two specimens are prepared in a regular way of placing shear reinforcement, the third specimen is made by ...

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.
