This research aims to evaluate how different configurations of NSM-CFRP strips affect the flexural strength of lightweight reinforced concrete beams.
Utilized four simply supported lightweight reinforced concrete beams with a rectangular cross-section.
Applied monotonic four-point bending tests to evaluate structural performance up to failure.
Compared three configurations of NSM-CFRP strips: two at mid-span, two along full span, and one along full span.
Two horizontal strips at the middle half of the beams increased ultimate load by 7.14%.
Two horizontal strips at full span increased ultimate load by 12.55%.
One horizontal strip at full span increased ultimate load by 9.35%.
All beams exhibited pure flexure failure, with concrete crushing and epoxy bonding failures observed.
