Abstract
The deterioration of concrete structures subjected to aggressive and
industrial environment has always been a major engineering problem, this
deterioration accelerates the corrosion of steel reinforcement which in
turn leads to more deterioration and most of the time to catastrophic
situations. With the Fusion Bonded Epoxy Coated Rebars (FBECR) that
can resist this aggressive environment for larger time that enable to have
a good structure for the required life time. So, it is very important to
study this kind of steel in different R..c. sections under different stresses.
The thesis deals with the study of general deformational behavior
of simple R.C. beams reinforced with (FBECR), under the effect of two
concentrated loads which cause bending and shearing stresses through
different stages of loading from zero up to the failure load level.The experimental phase of this study including the results of tests
conducted on five series (13-beams ) of simple concrete beams, with
constant concrete dimensions (200x 17x30cm), the variables in the
experimental program were the shear span-to-depth ratio’ aid’, stirrups
spacing’S’, percentage of longitudinal reinforcement ’p’{with the
absence of stirrups), and the type of reinforcement.
The analytical phase included the using of non-linear Finite
Element Method, taking into consideration the nonlinear stress-strain
curves of both concrete and steel, as well as the bond slippage between
steel and concrete.
The results of both experimental and analytical investigations,
including the cracking, crack propagation, failure loads, deflections and
strains were presented, discussed and compared.
Finally, the results of this experimental and theoretical study were
combined with other available information to formulate some
recommendations for the analysis, design, construction and economy of
using Fusion Bonded Epoxy Coated Rebars.
