The research aims to study the possibility of using practical methods to monitor the
geodetic vertical deformations, and to study the engineering of the origin of the
strengthened carbon fiber. Because of proposed changes in the construction status
of some
of its elements, the study will be accompanied by simulation of the proposed changes by
adding additional live and dead loads, that are equivalent to the new situation. This study
will be made by measuring the vertical displacements for some points of those elements
within optimal control network based on geodetic network confidence requirements. This
study will also assess the potential use of electronic digital high accuracy levels and the
supplied software.
The research succeeds in showing the possibility of quantifying the potential
deformations in reinforced elements, as well as the efficiency of the proposed method of
control and the equipment used.
This research aims to study the efficiency of flexural strengthening of RC beams with different lengths of CFRP strips by using (NSM) technique. The study is carried out experimentally on (14) concrete beams; the variables considered are (the length
and number of CFRP strips). This is established by dividing the work into two groups: the first one includes (6) beams strengthened by variable carbon fiber strip lengths and one strip, The second group includes (6) beams strengthened by variable carbon fiber strip lengths and two strips, as well as two control beams. The results indicate that carbon fibers have a noticeable effect on increasing the bearing capacity of (NSM) strengthened beams. The results also show that strengthening the beams by CFRP and not along the length of the beam and in one layer does not contribute to increasing beam strength, but when the number of layers increases, an increase in beam strength is noticed at a rate range (40%-72%).
