Diagonal ZeroZero Tower for the New Telefonica Headquarters in Barcelona, Spain

摘要

The 27 storey high ZeroZero tower in Barcelona (of which 25 floors are above ground level) reaches a height of 118 m (110 m above ground level). Its basic structural arrangement corresponds to a "tube-in-tube" type system, consisting of a double vertical tube system formed by the inner core working together with the facade, connected through the floor slabs. Even though the core is the fundamental resisting element for the horizontal loads, the contribution of the facades, formed by a double assembly of inner vertical columns and outer sloping elements, is essential.
