Analysis of CFT, RCC and Steel Building Subjected to Lateral Loading

Steel–concrete composite columns are used extensively in modern buildings. Extensive research on composite columns in which structural steel section are encased in concrete have been carried out. In-filled composite columns, however have received limited attention compared to encased columns. In this paper a comparative study of 10, 20 and 30 storey Concrete Filled Steel Tube (CFT), R.C.C. and Steel building is done. Comparison of parameters like time period, displacement, base shear and load carrying capacity is done with steel and R.C.C structures. Result shows CFT building is good in load carrying capacity with small cross section of column.
