Abstract EN
The main objective of this research is to study the effect of carbon fibers used to strengthen the joints of the box segmental beams.
For this research, four beams were produced and tested.
One of these beams, monolithically, was cast as a reference beam and the three others were segmental beams.
All beams were produced with Self-Compact Concrete (SCC) and box cross section.
Each segmental beam consisted of three precast concrete segments were connected by post tensioning tendons.
The three segmental beams have same characteristics, but different in joint types between the segments.
The types of joints used were (dried , epoxied and dried strengthen by CFRP sheets).
All beams were tested under static two point loads up to failure.
For each test, deflections at mid-span location were recorded for each (5kN).
Also, first cracking, mode of failure and ultimate loads values were recorded as well as the concrete surface strains at the specified locations for both loadings.
