The Concrete filled steel tube (CFST) has many advantages as compared to conventional RCC structure. One of the main advantages is provide high strength to the structure in small section size of column also it gave more stability in seismic behaviour. Also, one of main advantage as compared to conventional system it gave more life span to the structure. Now a days in China the CFST structure are extensively used such as the world High altitude level Railway arch bridge constructed in Tibet province of China and also Japan is the one of the countries research projects on this system over last 37 years the famous program conducted by US-Japan partnership is US-Japan comparative earthquake research program. This paper introduces the merits of CFST structure in new construction trend of CFST and discusses the results of trail design CFST and also finds out the ways to how to be more economical the CFST structure using mild steel in specimens and increase performance of the structure. this paper is based on comparative study of CFST and RC column under an axial compressive stress
