Designed by innovative engineer E A Cowper in 1854, it was found that curved or arched trusses
were stronger than traditional, triangular trusses and allowed for broader roof spans.
The most notable reminders of its period past are the exposed arched trusses
to the first floor and triangular topped windows.
Well-insulated bands of composition board are wrapped over the arched trusses
, and seven prefabricated shapes are used in different configurations to suggest a greater complexity of form.
The Loudenslager Stephens Akro Laser 200 was lifted by crane and hung by cable from one of the aviation hangar's ten-story-high arched trusses
. The aviation hangar--with a length of three football fields--will ultimately display some 200 aircraft.
The laminated wood arched trusses
are 27 ft above the ice at the bottom chord, and 47 ft high at the top of the arch.
The undulating roof structure is no less inventive, hung from huge arched trusses
that span yirtually the width of the market hall.
The basic approach is simple: arched trusses
of triangular cross section span the whole width of the huge space at 25 m centres.
