The central tower of a new high-rise city in the emirate of Ras Al-Khaimah rises 875 m into the sky, including the antenna. Its load-bearing structure consists of an outer cone-shaped network of steel profiles connected to an inner steel tube. The conical shape of the outer shell is articulated like the thread of a screw by a recess in the facade that winds upwards.
Outer Shell Like the Thread of a Screw
Every 25 m, the floor slabs are formed as a rigid transverse bulkhead to improve the torsional rigidity of the building. As a further special feature, the building has large-scale, column-free sky gardens on four levels. For this purpose, the loads of the columns above are distributed to the inner tube and the outer shell by means of diagonal struts.
