Steel Structures

Composite Structures

Advantages

  • Ιndustrial product (standardized)
  • Recyclabe material
  • Free to form any shape of section
  • High ratio of strength to weight
  • High ratio of stiffness to weight
  • Possibility to bridge very long spans
  • Possibility to install electromechanical hardware throughout the beams
  • Low maintenance costs
  • Environmentally friendly material
  • Requirement for fewer and smaller columns
  • Requires small foundation due to reduced self weight
  • Excellent seismic behavior
  • Rapid construction and erection
  • Possibility of replacement of damaged members
  • Consistent, stable and invariable mechanical properties over time
  • Posibility to disassemble the structure and resassemble it to another place
  • Great potential to change existing structures and expand


Disadvantages

  • Needs fireproof (not always)
  • Requires greater expertise

Further advantages beyond the advantages of steel structures

  • Multiple stiffness
  • Greater strength
  • Feasibility to reduce the height of beams
  • Feasibility to construct slabs without scaffolding


Disadvantages

  • Needs fireproof (not always)
  • Requires greater expertise and specialization
