Steel Beam Design – Basic Considerations and Important Factors

[Steel-detailing-services]

Steel beams are structural members mainly used as supports. Steel
beams are sometimes made up of an alloy of carbon and iron which is
popular for its strength. Beams are key to the support of a building,
laying out the load of the building laterally to ensure that it is
equally distributed, so that the building will not be prone to sagging
or buckling. Steel is a widely used material for beams for a number of
reasons, not least of which is that it is extremely strong and can
therefore be used in structures which would otherwise be regarded
structurally unsafe.

When architects design a new building or intend to renovate a present
one, they have to think about where beams are going to be placed and
what materials they are made from. Steel beams are standard in many
types of construction for their strength, with engineer deciding a
placement which meets structural and aesthetic needs. Engineers and
architects also make additional calculations which consider the total
weight of the building, distribution of open space in the building and
seismic activity in the area where the building is situated, as all of
these can affect structural integrity.

Steel beams must be both strong and stiff. The aim of the structural
design of beams is to make a choice of a beam for a specific purpose
then test by established mathematical procedures - whether the beam is
strong enough and the beam is stiff enough.

The behavior of a beam is mainly affected by the loading, span, how it
is supported, its cross-section and material used. For the same span
and loading, three things affect the performance of a beam - the
properties of the material, the way the beam is supported and the
geometry of the beam cross-section.
