The Concrete Filled Steel Tube (CFST) Structural System is a completely new system based on filling steel tubes with high-strength concrete. A CFST member contains two materials with different stress-strain curves and distinctly different behavior. The interactions of the two materials give difficult problems in the determination of combined properties such as moment of inertia and modulus of elasticity. The main objective of this research is to determine compression behavior of CFST with ordinary concrete and high strength concrete under axial load and emphasis on identifying behavior of relevance to offshore applications. The CFST specimens were tested under axial load to clarify the effect of the test parameters on the behavior. The tested samples of CFST were observed and discussed in this report.
