Abstract EN
This research based on experimental work included testing of thirteen specimens categorized into two groups.
The first group included five beams: one is solid while the others are hollow beams with two openings of different sizes and locations.
The second group included eight specimens strengthened with CFRP sheets in three systems to determine the best configuration of strengthening.
The experimental results showed that the presence of openings (150*150) mm and (150*250) mm, which located flushed to the flange, led to a decrease in the load capacity by (43% and 64%) for the square and rectangular openings respectively.
On the other hand, when the openings located in bottom location the reduction in capacity was found to be (48% and 70%) for the square and rectangular opening respectively.
Also, the results of the test showed that the strengthening of the carbon strips led to improving in the structural capacity, where in the case of openings located flushed to the flange, there was an increased by (19 % and 64 %) for square and rectangular openings respectively.
In contrary, in the case of opening located in the bottom location, the improvement in capacity was found to be (37 % and 87 %) for square and rectangular opening, respectively.
