Steel Frame

A steel frame refers to the building technique with a steel
skeleton. Vertical steel columns and horizontal I beams are
constructed in a rectangular grid. This grid frame supports the
attached walls, floors and roof of the building. The development of
the steel frame technique has made the construction of sky
scrapers possible.

The cross section of steel columns has a shape similar to the
letter H. the two flanges of the column are thicker and wider as
compared to the flanges on a beam. This makes it better to
withstand compression stress on the building structure.

Square or round steel tubules can be also used. They are often
filled with concrete. Steel beams are connected to the columns
with fasteners and bolts. The steel web in I beam is wider than
column web to resist higher bending stress and moments that
occur in beams.
