Determination of strut-and-tie models for structural concrete under dynamic loads
Canadian journal of civil engineering (Print), 2019 This proposed study aims to develop reliable and efficient numerical optimization methods for generating optimal strut-and-tie models (STMs) in structural concrete members under dynamic loads. The numerical models are developed based on the bidirectional

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 ...

Pre‐failure behavior of continuous post‐tensioned and post‐grouted beam in case of tendon failure
Structural Concrete, EarlyView.Abstract Grouted tendons are a common solution for long‐span bridge structures. The grout provides bond and corrosion protection for prestressing steel. However, if the grouting is defective, corrosion of the prestressing steel may initiate and eventually lead to tendon failure.

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

Structural Concrete, EarlyView.Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

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 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

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 ...

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.
