Sažetak
Many engineering structures have been built or are still being built out of reinforced concrete. When required, the strengthening of such structures due to the need for additional reinforcement or retrofitting damaged parts the use of fiber reinforced polymers (FRP) has become very efficient. This paper describes performed initial experimental and numerical investigations of reinforced concrete (RC) beams strengthened with carbon fiber reinforced polymers (CFRP), [1-2]. Two sets of RC beams have been tested. The first set consist of two identical RC beams (L×b×h = 1000 × 100 × 200 mm) made of concrete C30/37, reinforced with 2ϕ6 in the upper zone and 2ϕ10 in the lower zone, with stirrups. The second beam was strengthened with CFRP strip throughout the whole bottom, [1]. The second set consist of three identical RC beams (L×b×h = 1000 × 100 × 200 mm) made of concrete C25/30, reinforced with 2ϕ10 in both zones, upper and lower, with stirrups. The second beam was strengthened with CFRP strip throughout the whole bottom while the third beam was strengthened only in the mid 500 mm, [2]. All tests have been performed with the same equipment in the Laboratory for Testing Materials of the Civil Engineering Institute in Split. Tested RC beams after failure can be seen in Figure 1. To verify obtained test results, numerical calculations have been carried out with programme SCIA Engineer, [3].
