Generali Tower in Citylife Development, Milan
ACI EXCELLENCE IN CONCRETE CONSTRUCTION AWARD - WINNER IN "HIGH-RISE BUIDLINGS" CATEGORY!
Generali Tower was awarded the international ACI (American Concrete Institute) “Excellence in Concrete Construction Award” for the "High-Rise Buildings" category, during the Convention held in Cincinnati (Ohio) on October 21st 2019.
The motivation mentions: “the plan and engineering knowledge with the recognition of the design daring and characteristics and of the innovative methods of analysis which allowed for the high rise building realization”
Winners of the 2019 Excellence in Concrete Construction Awards
The tower rises 170,36 m above ground level and 185,96 m above foundations level (44 floors + 3 floors basement), with a total floor area of about 70.000 m².
The geometry of the building is that of a warping shape, where both the floors dimension and their orientation vary along the tower axis, according to mathematical expressions that rule the geometric parameters.
The structure is concrete and composite (concrete and steel).
A central core acts as main horizontal stiffening and resisting element; the slabs are cast in situ r.c. plates and the columns are also r.c., heavily armed sections. HPC with characteristic strenght up to 75 Mpa are widely used in teh columns.
Foundations are of mixed raft + piles type, where the piles are used as settlement reduction devices. The base raft is a 2,5 m thick concrete slab, resting on 64 piles (D1500mm L=36m) aranged in clusters and points under the main load points.
In order to resist the main torsional effects due to the warped column arrangement, the core lintels above main doors feature composite solutions with a mixed use of steel elements, rebar and concrete. Due to the specific form-dependent deformation effects, a highly sophisticated stage analysis both for construction and long term effects has been effected.
