Palazzetto dello Sport in Rome is a work of Annibale Vitellozzi projected in 1956 in collaboration with Pier Luigi Nervi, which
was built between 1956 and 1957 for the 1960 Olympics. The project consisted of a circular system of 60 meters in diameter.

9. Structural detail
◦ The cover is made of reinforced concrete prefabricated modules and wedge-shaped.
◦ The Palazzetto dello Sport is constructed with prefabricated ribbed concrete shell dome 61m in diameter, braced by
concrete flying buttresses.
◦ The principles of isostatic stress to minimize the material requirements of steel-reinforced, concrete, long-span
structures.The pre-cast, vaulted ribs and fan-shaped, ribbed support columns of this 330 ft. dome follow the isostatic lines
of principle stress, those in which theoretically no shear stress is induced, thus reducing the total use of concrete.

10. The ribbing of the dome and fans also provide a lateral loading system, by
maximizing the cross-sectional area of the dome, accommodating for asymmetrical
loading conditions.
Nervi’s plastic use of steel-reinforced concrete expressed the lines of principle
stress with a marriage of aesthetics and engineering efficiency. By slowly
deconstructing the Palazzo dello Sport, we may trace the primary force members
(from the dome through its 48 fanned structural members and inclined support
columns) as they transmit their load to the foundation along the tangent plane from
the thrust of the dome, seating banks and peripheral gallery.

15. The approach that was used to analyse the Palazetto Della Sport
and Ponte Della Musica was partly observational and partially
investigative research. Observational analysis included day
lighting analysis, structural analysis and a study of materiality.
One interesting observation that was made by studing day
lighting of the Palazzetto della Sport was that because the form
and use of glazing yielding to the ideal of radial symmetry the
building ignored southern exposure. The investigative research
included a geometric study of the reflected plan of Palazzetto
della Sport.
