The basic principles for structural design with aluminum are similar to
those for design with steel. Consideration needs to be made for the
reduced elastic modulus of aluminum, which means reduced buckling
strength and stiffness. In aluminum the strength of welds and the
adjacent heat-affected-zone are significantly less than in the base metal,
and the designer needs to be aware of this. Design codes generally
address the issue of weaker welded properties by designing all of the
structure for this reduced strength, although there are instances when
the properties of the base metal are used.
