Analysis of the nodal stresses in pile caps

Revista IBRACON de Estruturas e Materiais, 2018
Pile caps can be dimensioned using, preferably, plastic models (strut-and-tie) and models based on the flexion theory. In order to analyze the behavior of the stresses in the lower and upper nodal regions of the cap, a theoretical analysis of the ...

Analysis of the influence of supplementary reinforcement on the behavior of reinforced‐concrete two‐pile caps subjected to concentric and eccentric loading

Structural Concrete, EarlyView.
Abstract This article examines the behavior of reinforced‐concrete pile caps on two piles under concentric and eccentric loading, with emphasis on the influence of horizontal and vertical supplementary reinforcement on load‐carrying capacity. Although the Strut‐and‐Tie method does not include this reinforcement in the internal equilibrium, it was found

Comparison of STM’s reliability system on the example of selected element

Open Engineering, 2020
This paper presents optimization of the reliability system for different Strut and Tie models of beams loaded with a torsional and bending moment. In this paper, three STMs depending on the angle of diagonal strut were compared. The presented beam models

Influence of mix design method on the shear capacity of reinforced concrete beams made with high‐quality recycled coarse aggregate

Structural Concrete, EarlyView.
Abstract This study investigates the shear capacity behavior of reinforced concrete (RC) beams without stirrups incorporating recycled coarse aggregate (RCA). An extensive database comprising 269 experimental data points from 40 journal articles published between 2001 and 2025 was compiled, excluding specimens with recycled fine aggregate or fiber ...

Alternative Strut and Tie Model for Reinforced Concrete Deep Beams

مجلة النهرين للعلوم الهندسية, 2018
This paper presents a simple strut and tie model to calculate the shear strength of reinforced concrete deep beams. The proposed model assumes that the shear strength is the algebraic sum of three strength components: concrete diagonal strut, vertical ...

Structural capacity of precast concrete walls with openings: A parametric study on connection types and reinforcement ratios

Structural Concrete, EarlyView.
Abstract The structural role of precast concrete walls with openings is often overlooked in design practice due to concerns about reduced stiffness, stress concentration, cracking around openings, and potential unexpected failure modes under seismic loading.

Reverse engineering strut‐and‐tie models for assessing reinforced concrete structures

Structural Concrete, EarlyView.
Abstract Strut‐and‐tie models enable the design of reinforced concrete structures with static or geometrical discontinuities, providing interpretability and control over the load path. These models are valuable for designing discontinuity regions of new structures and for validating nonlinear finite‐element analysis results. However, developing a strut‐

The influence of secondary reinforcement on a strut‐and‐tie model for the design of reinforced concrete corbels

Structural Concrete, EarlyView.
Abstract In precast concrete structures, optimizing the design of corbels by considering the contributions of secondary reinforcement elements can significantly improve construction economy, especially when corbels are repeated multiple times. This paper proposes a strut‐and‐tie model for reinforced concrete corbels subjected to vertical and/or ...

Optimized Design of Anchor Plates for 2200 MPa-Class Prestressing Anchorage Zones

Buildings
The strength of prestressed steel strands has developed towards high strength, increasing from 1860 MPa to over 2200 MPa. The stress in the prestressed anchorage zone is more concentrated and complex, and the anchor plates for dispersed loads need to be ...

Analysis of nodal stress on reinforced concrete two-pile caps supported on steel piles

Revista IBRACON de Estruturas e Materiais, 2020
: Reinforced concrete pile caps may be designed trough plastic models (strut and tie model) or models based on bending theory. The formulae available for verifying the stress is based on caps supported on concrete piles, with few studies about the stress
