The improvements in material properties, which improve structural performance, have extended the use of fibre-reinforced concrete to applications in the area of fire. The presence of micro cracks in the mortar-aggregate interface is responsible for the inherent weakness of plain concrete. The weakness can be removed by inclusion of fibers in the mixture. Different types of fibers, such as those used in traditional composite materials can be introduced into the concrete mixture to increase its toughness, or ability to resist crack growth.Since the present design methods and approaches are limited to the property, strength, stiffness and ductility of PCC in-filled columns and beams this study will provide the detailed investigation of the actual and local, post buckling and flexural behavior of SFRC in-filled light gauge steel box columns and beams subjected to various typical load conditions. The wider use of light gauge structural components in many areas of application has promoted considerable interest in the in-filled light gauge members. The main target of the examination is to investigate the conduct of hollow, Plain Cement Concrete (PCC) and Steel Fiber Reinforced Concrete (SFRC) in-filled stub, short and medium columns subjected to axial and eccentric loads and bars subjected to flexure. Trial, Theoretical and Numerical investigations have been completed. In the principal stage, trial investigations were completed to contemplate the conduct of hollow, PCC and SFRC in-filled light gauge steel stub, short and medium stature columns. 78 investigations were directed, out of which five tests were on stub columns, five tests were on short columns and 68 tests were on medium tallness columns.
