Abstract

Flexural strengthening of RC beams using carbon fiber composite (CFRP) sheets is a solution that shows many advantages in comparing to traditional strengthening solutions. The main goal of this study is to examine the effects of initial load on the effectiveness of strengthening by externally bonded CFRP laminates. Two identical beams were tested. One beam was used as control specimen while one other beam was strengthened in flexure under sustaining load. The value of the intial load was determined on the basic of cracking of concrete in tension zone, with crack width value is 0.3 mm. The obtained results have shown that for RC beams that are already cracked and deformed under sustaining loads, the effectiveness of CFRP strengthening can be demonstrated by the significant increase in the flexural stiffness and the load-carrying capacity of the strengthened RC beams.
