chosen for its sound insulating
qualities – coloured a soft grey.
The cantilever doubly curved roof
is a steel space truss: three arches
in high tensile steel span the
building between two concrete
piers. The arches have tapered
wide flange cross sections which
have a maximum depth of 27 in
at the apexes.
The steel space truss resists
the roof deadload of a 4 in thick
lightweight concrete slab: this is
cast on steel mesh and finishes
flush with the top surface.
Under live load the concrete roof
and supporting space trusses act
compositely.
Steel tubes – maximum diameter
8 in – for extra heavy cross
sections form the longitudinal,
diagonal and edge members of the
cantilever spans. Gusset plates at
the connections of the tube resist
shear stresses between truss

and concrete deck, so ensuring
composite action. The building is
in Marina City, Chicago and was
designed by Bernard Goldberg
Associates, architect-engineers of
that city. The unusual roof was
designed by Hannskarl Bandel,
Severud Associates, New York.
