Space Frames ~ these are roofing systems which consist of a series
of connectors which joins together the chords and bracing
members of the system. Single or double layer grids are possible,
the former usually employed in connection with small domes or
curved roofs. Space frames are similar in concept to space decks
but they have greater flexibility in design and layout possibilities.
Most space frames are fabricated from structural steel tubes or
tubes of aluminium alloy although any suitable structural material
could be used.Typical Examples~Long Span Roofs
