What is Steel Structure and It’s Advantages

Definition & Scope

  • A structure which is made from organised combination of structural steel members designed to carry loads and provide adequate rigidity.
  • Steel structures involve sub-structure or members in a building made from structural steel.
  • Structural member is physically distinguishable part of structure with independent structural function, e.g. member, element, cable and their combination.

Advantages of Steel Structure

  • High strength.
  • The high ratio of strength to weight (the strength per unit weight).
  • Excellent ductility and seismic resistance.
  • Withstand extensive deformation without failure even under high tensile stress.
  • Elasticity, uniformity of material.
  • Predictability of properties, close to design assumption.
  • Ease of fabrication and speed of erection.
  • Susceptibility to corrosion.
  • Maintenance costs / thin-walled structure.
  • Loss of strength at elevated temperature.
  • Fireproofing costs.
  • Susceptibility to buckling.
  • Slender member in compression.
  • Fatigue and brittle fracture.

Where & when use steel structures

  • Long-span structures
  • Multi-storey & high-rise buildings
  • Buildings of heavy duty plants
  • Tower & mast structures
  • Portal frames
  • Bridges
  • Infrastructures
  • Deployable structures
  • Generalized structures: mechanical


One Comment on “What is Steel Structure and It’s Advantages”

  1. It was interesting to learn that structural steel has high strength and withstands corrosion well. I imagine you’d need to invest in structural steel from a supplier with many years in the industry. That way, you can trust that they know what they’re doing and will provide the best quality products.
