Numerical Analysis on Structural Behaviour of Concrete-Filled Steel Tubular Columns
Concrete-filled steel tubular (CFST) member is a composite of infilled concrete core and outer steel tube. In recent decades, CFST members has paid high attention to the researchers due to many reasons. CFST technology uses the benefits of both concrete and steel to increase the strength capacity. The experimental study is quite limited due to scarcity of laboratory facility and test time consumption. Therefore, this paper deals with the validation of the experimental data using numerical software ABAQUS to figure out the mechanical and confinement behaviour of the CFST columns. A total of 15 CFST columns (stub and slender) have been taken with three different shapes which are categorized as circular, rectangular and square sections. The CFST columns were made with different concrete strength, slenderness ratio. The simulation results were verified with the experimental data. From the comparison, it is noticed that the numerical results can accurately capture the experimental results. It is also observed that the confinement on lower strength concretes was higher than the higher-grade concrete strength.
