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‐

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.

Exploring the potential of Textile Reinforced Concrete for corrosion‐insensitive retaining walls
Structural Concrete, EarlyView.Abstract In a context where durability concerns, particularly the corrosion of steel reinforcement, remain a critical challenge for conventional reinforced concrete structures under severe exposure, Textile Reinforced Concrete (TRC) is emerging as a promising alternative.

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa
Structural Concrete, EarlyView.Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.

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‐
