Axial Capacity of Encased Composite Column Under Axial Loading

The Encased composite column is one of the best option in the design of high-rise building where building load is heavy and architect restrict the increase the size of column. Encased column has high resistance to fire load and blast load. Rolled I-section is used in composite column because in built-up section there is more cost in fabrication and the cost of connection between the beam and column is very high. In a country where this technology is developed, it is used in design of important structure. In this paper analytical equation are discussed related to design of Encased composite column under axial loading. Besides comparison between the British Code and IS Code has been carried out that would result in more economical and serviceable structure.
