Abstracts : The present research concentrates about
compare the behaviour of concrete filled FRP tubes
under different grades of concrete. Evaluate the
behaviour of concrete filled FRP tubes using central
holes with and without an inner PVC pipe. To evaluate
both fully and partially concrete filled FRP tubes attain
the axial compressive strength, tensile load and
Modulus of elasticity. Comparison of strengths for the
above cases and suggesting the effectiveness of FRP.
Compared with conventional concrete
cylinders, FRP tubes filled with concrete attains a
compressive strength, which is 87 % higher that of
conventional concrete cylinders. Strength and ductility
are greatly improved by filling the tubes with concrete.
FRP tubes were more efficient than steel tubes in this
regard. Concrete in the compression zone is partially
confined as evident by the lateral tensile strains
measured on the shell. If the hole is maintained by an
inner PVC pipe, the confinement effectiveness is
improved and could approach that of a totally filled
tube. It can be observed that there is significant
improvement in Cylinder Compressive Strength, Split
Tensile Strength and Modulus of Elasticity compared
to PVC Shells. The Percentage increase in Compressive
Strength for M20 Grade of Concrete with Central Hole
dia of 0mm, 50mm & 75mm are 87.76%, 54.31% and
71.11 respectively. Similarly, for M25 Grade of
Concrete with Central Hole dia of 0mm, 50mm &
75mm are 106.93%, 81.79% and 93.46% respectively.
