- 7. ADVANTAGES OF STEELCOLUMN High Strength : This means that the weight of column that made of steel will be small. Uniformity: Properties of steel do not change in any portion of Column. Ductility : Steel can withstand extensive deformation without failure under high tensile Stresses Toughness : Steel has both strength and ductility
- 8. DISADVANTAGES OF STEELCOLUMN The use of steel columns is very economical because of their high strength and slenderness of a compressive column is increased, its danger of buckling increases The strength of structural steel member can be reduced if this member is subjected to cyclic loading. Under certain conditions steel may lose its ductility , and brittle fracture may occur at places of stress concentration.
