Buckling Analysis of Silica Fume Concrete Filled Steel Tube Column using ANSYS

In composite construction, the concrete and steel are combined in such a fashion that the advantages of both the materials are utilized effectively. The lighter weight and higher strength of steel permit the use of smaller and lighter foundations. Concrete filled steel tubes having high load carrying capacity where as when silica fumes is mixed with concrete increases its performance. The subsequent concrete addition enables the building frame to easily limit the sway and lateral deflections. Hollow column has less self weight and a high flexural stiffness and hence its usage in seismic zone proves promising. . In this study silica fume concrete (SFC) is used as an infill material instead of normal concrete in steel tube columns. It reduces requirements on labour, construction time and formwork also maintains the construction quality.
