DOI: 10.1016/j.jobe.2020.101772
Abstract: Abstract The efficiency of using side near-surface mounted (SNSM) carbon fiber reinforced polymer (CFRP) strips with a variable profile in strengthening reinforced concrete (RC) beams is studied. RC beams (150 × 250 × 1400 mm) were strengthened using straight, trapezoidal,… read more here.
