An Experimental Investigation on Light Gauge Steel Hollow Circular Column infilled with Nano Concrete
This paper deals with the axial load carrying capacity of light gauge steel hollow circular section infilled with Nano concrete. Among the various infill materials, Nano silica is gaining attention in the concrete-filled steel tube (CFST) columns. The main objective of this paper is to study the axial load carrying capacity, relation between the steel and concrete interaction and also the characteristic of hollow steel column, plain and Nano silica infilled steel columns, load–deformation, load–axial strain and load–axial shortening of CFST columns. Nano silica was optimized as 2% in the Nano concrete based on the tests conducted. A total of 21 specimens were tested with a dimension of 50 mm diameter, 1.5 m length and the thickness of the steel tubes were taken as 1.2, 1.6 and 2.0 mm. Experiments were carried out with M30 grade of concrete, and finally, these experimental results are evaluated, and the experimental values are guide lines available validated with the existing codes such as Eurocode4 (EC4-2004), British code (BS5400-2005) and American code (ACI-1999).
