Multi-storied steel buildings have un-matched benefits like:
- High strength to volume / mass ratio.
- Speed in construction and time-saving in comparison to RCC structures, directly resulting in an early return on
- Steel frames are lighter in weight in comparison to the RCC frame. Lighter foundations are required for steel building due to less weight than RCC resulting in cost advantage over civil construction.
- Occupies less space and can be designed for larger span/column-free spaces, resulting in greater coverage, this helps in large open office spaces and large auditoriums and concert halls, etc.
What Is High-rise?
Building a high-rise or any multi-level building demands the use of lightweight yet strong materials. Steel, by virtue of its high strength to weight ratio, enables large spans and lightweight construction. Steel structures can give a variety of structural forms like braced frames and moment resistant frames suitable to meet the specific requirements of higher buildings. Taller buildings also face higher wind loads, and hence steel being flexible, allows the building to move and deflect with the wind forces, rather than making it rigid like concrete.
Tall buildings with steel also allow more floors per the total height of the building. This is due to the fact that the building structure in steel is lighter and more efficient, and has beams that are not required to be as deep as those of concrete to support the floor. The ability to have lighter sections, allowing the same load-bearing capacity per floor, allows space for almost 1.5 extra floors in the same overall external height of the building.
