Abstract
The main goal of this research is to evaluate the mechanical efficiency of the
locally available bonding materials in Egypt used to bond carbon fibers to surface
of different steel elements for the reason of repair and strengthening.
To achieve this goal theoretical and experimental studies were carried out and were
illustrated in details throughout the different chapters of this thesis.
The experimental study carried out in this research was divided into two stages.
The first stage of the experimental work was to investigate the efficiency of the
aforementioned bonding materials by testing specimens intension, single shear, and
double shear. The first stage was carried out on two commonly used materials in
the Egyptian market, denoted to as I and II bonding materials. The experimental
results obtained in this stage were used to establish the efficiency of these two
bonding materials with carbon fiber laminates on steel members.
The second stage of the experimental work was to investigate the efficiency of the
best bonding material (based on the results of stage 1) through testing of four full
scale beams.
The first beam, denoted to as CL, was the control beam. All the results of the other
three beams were compared with the results of this control beam. The second beam,
denoted to as ST, was a steel beam strengthened by carbon fibers using the best
bonding material as mentioned before. The third one, denoted to as RP, was a steel
beam with a cut in the lower flange and was repaired using the same carbon fiber
laminates and bonding materials mentioned before. The last beam, denoted to as
FS, was a steel beam fully cut and fully spliced by CFRP
