- Abstract:
- In this paper, we investigate concrete beam behavior in FRP composite layering under incremental loading. In doing so, we examined four beams with cross section of 200 mm, height of 150 mm and length of 2300 mm. Of these four beams, three were strengthened by FRP sheets with various layer numbers and one was set as the benchmark. The laboratorial samples of the second series were beams with cross section of 150 mm, height of 200 mm and length of 2000 mm. We strengthened the samples by CFRP sheets with various widths and layer numbers and set the other two as benchmark. We examined the standard cylindrical samples and the strengthened and control beams under incremental loading. For this purpose, we prepared force-displacement diagram and studied their load failure. We also compared the results of laboratorial and theoretical studies. According to the results, the use of FRP sheets increased flexural capacity and stiffness of beams, reduced the number of cracks and their opening and concentrated the failure on sheet rupture point. Moreover, the investigation of force-displacement diagrams indicated the satisfactory performance of the strengthened beams in repeated loading and good coordination between theoretical and laboratorial relations. © Research India Publications
