TRM‐to‐concrete interface bond without anchors: Combined experimental, analytical, and numerical modeling approach

Structural Concrete, EarlyView.
Abstract Textile reinforced mortar (TRM) systems have emerged as an effective alternative to conventional FRP strengthening solutions due to their compatibility with concrete substrates and favorable performance under adverse environmental conditions.

Split‐disk testing of precast ultra‐high performance fiber‐reinforced concrete tubes

Structural Concrete, EarlyView.
Abstract Ultra‐high performance fiber‐reinforced concrete (UHPFRC) has great potential for structural applications involving precast cylindrical shapes, including pipes, silos and stay‐in‐place forms for concrete columns. This study examines the performance of UHPFRC rings under internal pressure simulated using the split‐disk loading method, along ...

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

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Simple and detailed modeling of corrosion‐affected slender shear critical RC beams

Structural Concrete, EarlyView.
Abstract The corrosion of steel bars compromises both the safety and the serviceability of reinforced concrete (RC) structures. Consequently, reliable tools are required to estimate the detrimental effects of corrosion on the structural response of RC members subjected to transverse loads.

Punching shear of unbonded post‐tensioned steel fiber reinforced concrete slabs: The fiber contribution

Structural Concrete, EarlyView.
Abstract Steel fiber reinforced concrete (SFRC) enhances the flexural capacity of flat slabs and, due to its effectiveness in statically redundant bi‐dimensional elements, represents a viable alternative to conventional reinforcement. Although numerous studies have investigated the flexural behavior of SFRC slabs with and without bonded reinforcement ...

From section to structure: Assessing the impact of localized corrosion on reinforced concrete beams

Structural Concrete, EarlyView.
Abstract The structural behavior of reinforced concrete (RC) elements affected by localized corrosion represents a major challenge for ensuring structural safety and for the proper design of strengthening interventions. The effects of localized corrosion on the flexural behavior of RC beams remain a topic of debate within the scientific community.

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.

Sensitivity study on accuracy and relevant parameters in numerical modeling of internal tendon breaks

Structural Concrete, EarlyView.
Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

A method for determining the performance of formulas for calculating the crack width and spacing in reinforced concrete elements

Structural Concrete, EarlyView.
Abstract Numerous studies have been conducted to determine the performance of formulas for calculating crack width and spacing in reinforced concrete structures. Generally, these studies pay limited attention to the application areas of those formulas and how to compare different representations of the crack width and spacing.
