Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete

Structural Concrete, EarlyView.
Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...

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.

Behavior of manufactured sand and recycled coarse aggregate concrete‐filled steel tubular stub columns with circular section

Structural Concrete, EarlyView.
Abstract Accelerated urbanization has intensified environmental concerns due to excessive natural resource consumption and construction waste generation. Circular concrete‐filled steel tube (CFST) columns incorporating manufactured sand recycled coarse aggregate (MS‐RCA) concrete have emerged as an innovative composite element offering notable ...

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

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.
