Flexural Behaviour of Locally Milled Steel Reinforced Concrete Beams with Tension Lap-Splices in Normal, Medium and High Strength Concrete

Jonathan Sasah, Charles K. Kankam, Jacqueline Obeng, Richard Akuaku & Ernest Kwadwo Dapaah · Asian Journal of Advanced Research and Reports · 2026

This study investigated the flexural behaviour of reinforced concrete beams reinforced with locally milled medium- to high-yield steel bars containing tension lap splices. The work examined the effects of lap length, concrete grade and bar diameter on tensile and flexural perform...

Strength Capacity Characteristics of Welded and Mechanical Couple Spliced Steel Bars for Reinforcing Concrete

Jonathan Sasah, Charles K. Kankam, Jacqueline Obeng, Richard Akuaku, Vincent Akortia & Ernest K. Dapaah · Journal of Engineering Research and Reports · 2026

Lapping, the commonest technique used to splice reinforcement bars, needs no special instrument or skill to execute. However, their usage may result in excessive section reinforcement, which may result in a non-ductile response of the spliced region. The structural performance of...
