Objective of the report Introduction Concrete filled composite columns Steel reinforced cancrete columns References End Introduction A composite or hybrid system is that one that combines the advantages of concrete and structural steel. By definition,columns are structural members which are subjected mainly to axial forces and very little transverse shear. Concrete Steel ■Rigid, ■High strength. ■Economic. ■Ductile. ■Fire resistant. ■Easy to assembly. ■Durable ■Fast to erect.
