Abstract

The paper presents an experimental study on the behaviour of axial loaded slender square concrete-filled high strength steel tube columns until failure. Four specimens were tested to investigate the effect of high strength steel and plain strength concrete on the load carrying capacity of the square concrete-filled steel tube columns. The effect of the concrete which filled in the steel tube was also investigated. The main parameters in the tests were: (1) the ultimate strength of steel (SM490 and HSB800), and (2) the presence of concrete in steel tube (hollow steel tube and concrete-filled steel tube). The main objectives of these tests were three-step: (1) to describe a series of tests on composite columns, (2) to analyse the influence of several parameters, and (3) to compare the accuracy of the predictions by using the specifications in the code (ACI, EC4 and KCI etc.) for the design of high-strength composite columns. Experimental results indicate that the ultimate strength of steel and presence of concrete had significant influence on both the axial compressive load capacity and the ductile of the square steel tube.
