To evaluate the flexural response and failure modes of concrete beams reinforced with steel, GFRP, and hybrid bars under different lap-splice configurations and material parameters.
Developed 16 finite element beam models in ABAQUS subjected to four-point bending and benchmarked against ACI 440 design provisions.
Evaluated the effects of reinforcement type (steel, GFRP, hybrid), splice length, number of spliced bars, concrete compressive strength, beam depth, and hybrid reinforcement ratio.
Beams without lap splices exhibited enhanced ductility, whereas shorter splice lengths and higher splice ratios caused more brittle failures.
Increasing concrete compressive strength and beam depth significantly enhanced flexural capacity and stiffness, while varying the hybrid reinforcement ratio had minimal impact.
Finite element predictions demonstrated close agreement with ACI-based design calculations across the analyzed configurations.
