 4.Overhanging beams
Column Ties
 An overhanging beam is one that is supported at two
different areas, typically at one end and in the middle
of the beam, but does not have a support at the
other end of the beam, leaving it hanging. This type of
beam extends beyond the walls or columns and the
overhanging section of the beam is unsupported. An
overhanging beam is a combination of a simply
supported beam and a cantilever beam.
Composite Beams
 5.Cantilever beam
 A cantilever beam is one that is free-hanging at one
end of the beam and fixed at the other. This type of
beam is capable of carrying loads with both bending
moment and sheer stress and is typically used when
building bridge trusses or similar structures. The end
that is fixed is typically attached to a column or wall.
The tension zone of a cantilever beam is found at the
top of the beam with the compression at the bottom
