ABSTRACT: The development of Concrete
Filled Plastic Tube (CFPT) Stub Columns, is commonly used in the areas where the concrete
structures interact with marine and saline environments, compared to regular
concrete columns. Several CFPT stub column samples were prepared to investigate
their behaviour under certain loading conditions. The main objective of this
study was to conduct an experimental investigation to observe the effect of
using CFPT with different diameters on the final strength of the concrete
columns. In order to achieve this target, two types of loading conditions were
applied, including separate load on the concrete and combined load on the
concrete and the plastic tube simultaneously. The study revealed a significant improvement in the compressive
strength of CFPT columns with different diameters (70 - 100 - 150 mm). Overall results show that the use of CFPT
columns provides better mechanical
performance compared to ordinary concrete columns. An evaluation of using the
available calculation methods to predict the load-carrying capacities of
CFPT. The study suggested the use of CFPT columns in situations where common
concrete may cause significant issues related to its deterioration and
disintegration in response to severe weather conditions.
