Near-surface mounted (NSM) fiber reinforced polymer (FRP) bars are becoming increasingly effective in strengthening and upgrading reinforced concrete (RC) beams. Most of the previous related works indicated that failure of the NSM FRP-strengthened be, embedded through-section (ETS) end anchorage technique is introduced to increase the flexural capacity of RC beams strengthened with NSM basalt fiberreinforced polymer (BFRP) bars. The ETS end anchorage technique was manually developed by forming a, whereas the remaining two specimens were strengthened utilizing NSM BFRP bars without anchorages. The axial stiffness of BFRP bars was kept constant for all strengthened beams. The beams were subjected to a four-point bending test until failure, and the results were evaluated. The experimental results revealed that using the proposed nonmechanical anchor significantly enhance the flexural capacity and post-yield stiffness of NSM BFRP-strengthened beams. Moreover, ETS end anchorage achieved 90% of the ultimate tensile capacity of the BFRP bars. The surface area of BFRP reinforcement and the number of the end anchorages had a significant impact on the load capacity of the strengthened beams
