Abstract

Recently, the concrete filled stainless steel tubes (CFSST) columns are widely applied in modern construction due to its aesthetic appearance, high corrosion resistant and less construction cost. The current study aims to evaluate the behavior of CFSST column with square hollow section (SHS) numerically under axial compressive load by using ABAQUS software. A good consistency had achieved between the numerical and experimental test results in terms of load-displacement behaviour and ultimate strength with a maximum difference equal to 2%. Intensive parametric studies had been conducted to determine the effects of stainless steel tubes and concrete properties on the ultimate load capacity of CFSST column. The results proved that the stainless steel tube thickness (t) capable to increase the strength of column by143.59% at t = 10 mm as compared with t = 2 mm, whereas a slight effect had observed for the variation of stainless steel proof stress (σ0.2). On the other hand, the higher values of concrete strength (fc′) obviously reduced the lateral expansion of CFSST column at initial load and led to increase the ultimate load capacity by 34.18 % at fc′ = 80 MPa as compared with fc′ = 30 MPa. Furthermore, the design strengths calculated according to the Eurocode 4 for concrete filled steel tube (CFST) column appeared a good agreement with the numerical results within an average difference value 2.49%, hence, it could consider as the most rational design method to determine the ultimate strength of CFSST column.
