Palazzo
dello Sport (Large Sports Palace), Rome
Designed by Pier Luigi Nervi
Built 1958
- 60
Historical Context:
The Palazzo dello Sport is a sports arena that was built by P.L. Nervi
for the 1961 Olympic Games in Rome. It is adaptable for a number of indoor
sporting activities, including Basketball, tennis, boxing, wrestling and
gymnastics.
Structural
Design Innovation:
Nervi's structurally innovative forms utilized 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. 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. The 48
inclined columns transmit the load to the foundation with in-plane forces
(along the tangental plane) from the combined thrust of the dome, seating
banks and periferal gallery.
"The
inclination exactly follows the resultants of the thrust of the dome and
of the vertical reaction due to the upper bank of seats and the roof of
the periferal gallery." -
