This paper analyzes the constructive solutions adopted for the steel floor of Palermo's Palasport, made up of a parallel array of 13 biconcave cable trusses supporting a roof rectangular in plane. The building was completed in 1999, but in 2008 it suffered serious damages due to the wind actions on the roof, which have made it unusable to date. Particular attention is paid to the evaluation of wind actions, according to the Technical Standards of Construction (D.M. 14/01/2008) and to the CNR DT 207/2088 Instructions. The original design solutions and those analyzed for the refurbishment are described, as well as static and dynamic structural investigations designed to characterize the safety conditions of steel structures.

Abstract
This paper analyzes the constructive solutions adopted for the steel floor of Palermo's Palasport, made up of a parallel array of 13 biconcave cable trusses supporting a roof rectangular in plane. The building was completed in 1999, but in 2008 it suffered serious damages due to the wind actions on the roof, which have made it unusable to date. Particular attention is paid to the evaluation of wind actions, according to the Technical Standards of Construction (D.M. 14/01/2008) and to the CNR DT 207/2088 Instructions. The original design solutions and those analyzed for the refurbishment are described, as well as static and dynamic structural investigations designed to characterize the safety conditions of steel structures.| File | Dimensione | Formato | |
