Conclusions
In the UK, cellular beams are the most popular
form of long-span construction
Long, column free spans are provided which
permit flexibility in the layout and more usable
floor area
Design software is freely available which permits
calculations to be made rapidly
Extensive structural, fire and in situ tests have
been undertaken over the last 10-years to develop
and validate the design software.
