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.

Kinematics‐based model for shear capacity assessment of unreinforced interior beam–column joints
Structural Concrete, EarlyView.Abstract This study presents a kinematics‐based model for assessing the shear strength of reinforced concrete interior beam–column joints without transverse reinforcement. The proposed framework is built on first principles—kinematics, equilibrium, and constitutive relations—and explicitly models discrete cracks by introducing kinematic parameters such

Rotation capacity of continuous reinforced concrete slab strips revisited
Structural Concrete, EarlyView.Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...

The challenges of GFRP RC beam design for limit states
Structural Concrete, EarlyView.Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

Structural Concrete, EarlyView.Abstract During their life cycle, prestressed concrete bridges are prone to wire breaks of their tendons due to fatigue or stress corrosion cracking. However, not all structures show visible cracking on the surface, which would provide timely warning of otherwise invisible damage. Brittle failure may occur.
