Abstract:
The 800 meter (730 yd) long bridge over Serio River is one of the most significant launched bridges in Italy, and one of the few in the world with a bi-cellular cross section. The control techniques required for long launched bridges is addressed. In particular, the author explains the effects of creep of the concrete during a long work stoppage of 21 months, and the remedies to restart and complete the launch.
