If outriggers are used, as is the case with the majority of masted structures, then
the lateral stability of the outrigger can be resolved in a similar form to the masts
by a stiff truss or Vierendeel section in plan or by plan or diagonal bracing at the
extremity (Fig. 5.11).
5.2 Space frames
5.2.1 Introduction
Steel skeletal space frames are three-dimensional structures capable of very large
column-free spans. These structures, constructed from either individual elements or
prefabricated modules, process a high strength-to-weight ratio and stiffness. Steel
space frames may be used efficiently to form roofs, walls and floors for projects such
as shopping arcades, but their real supremacy is in providing roof cover for sports
stadia, exhibition halls, aircraft hangars and similar major structures.
