Prediction of Axial Capacity of Hexagonal Concrete-Filled Steel Tube Columns
The present study aims to introduce a new method that gives accurate predictions of the ultimate capacity of hexagonal concrete-filled steel tube columns. Experimental data available in the literature were used to validate the new method. Also, it was used to construct a constitutive model for the core concrete that can be employed in the finite element analysis. This allows testing the model with the available experimental results of the behavior of hexagonal columns under concentric load. An extensive parametric study was carried out to explore the effects of different parameters on the behavior and ultimate capacity of the columns. The effects of the compressive concrete strength, yield strength of steel ratio and depth-to-thickness of the tube ratio were investigated. It is found that these parameters have significant effects on the behavior of the columns, for example a reduction in depth-to-thickness ratio from 33 to 17 gave a 100% increase in ultimate strength.
