Conventional steel buildings

Conventional steel construction could be considered the parent to pre-engineered steel buildings; both are still used in the industry to develop everything from small steel sheds to skyscrapers and wide, open-span facilities.Conventional steel buildings are traditional metal structures constructed by rolled steel sections which are designed individually and fabricated at site using welding and cutting. Steel provides several advantages over other building materials

  • Steel is structurally sound and manufactured to strict specifications and tolerances.
  • Steel does not easily warp, buckle, twist or bend, and is therefore easy to modify and offers design flexibility. Steel is also easy to install.
  • Steel allows for improved quality of construction and less maintenance, while offering improved safety and resistance.
  • With the propagation of mold and mildew in residential buildings, using steel minimizes these infestations. Mold needs moist, porous material to grow. Steel studs do not have those problems.

Following properties of structural steel are considered before using them for a construction. These properties are useful for determining the quality of steel. High quality steel is used so that dependable and long lasting construction is possible. The most important components include the following:

  • Density
    • Density of a material is defined as mass per unit volume. Structural steel has density of 7.75 to 8.1 g/cm3.

  • Elastic Modulus
    • Elastic modulus or modulus of elasticity is the measurement of tendency of an object to be deformed when force or stress is applied to it. Typical values for structural steel range from 190-210 gigapascals.

  • Poisson's Ratio
    • It is the ratio between contraction and elongation of the material. Lower the value, lesser the object will shrink in thickness when stretched. Acceptable values for structural steel are 0.27 to 0.3.
