Abstract
Concrete filled tubular section (CFT‟s) is a composite column of hollow steel and concrete filled into it. This composite action of concrete and steel gives better performance under service. CFT‟s carries higher loads as compared to steel column and conventional reinforced concrete, due to this property CFT‟s are highly recommended for tall structures. CFT‟s can provide more carpet area as compared to the RCC column due to cross section reduction in CFT‟s. Study shows that for high rise buildings composite construction is economical. CFT‟s are filled with normal concrete where the filling problems arise due to dense reinforcement or smaller cross section or the distance between two profiles are less, self-compacting concrete (SCC) can be recommended due to its workability. The previous researcher shows a comparison between normal concrete, SCC and light weight aggregate concrete inside CFT‟s with L/D and D/t ratios and different curing techniques for SCC
