Results are presented of an experimental program undertaken to investigate the effects of strain rate on the behavior of reinforce concrete (RC) beams strengthened with carbon fiber - reinforced polymer (CFRP) laminates. Nine 3-m RC concrete beams, one unstrengthened, four strengthened with S-type CFRP laminates, and four strengthened with R-type laminates, were loaded under four different loading schedules. The stroke rates ranged from 0.0167 mm/s 9slow rate of loading) to 36 mm/s (fast rate of loading).
