Torre Caja Madrid: cálculo de estructuras de un edificio singular de 250 m en Madrid

Torre Caja Madrid: structural design of a singular 250 m building in Madrid

Working closely with Foster and Partners, an astonishing column free base tower was created by supporting the entire weight of the building on only its two end cores. These heavily loaded cores allow the slender tower to efficiently resist wind loads. With a height to width ratio of 11 to 1, this 250 m tower is the ultimate in structural efficiency (See figure 1). To achieve this unique structure, steel trusses at intermediate mechanical levels channel loads from the floors above to the cores and serve as beams in a ?mega-frame? to stiffen the tower. Special attention was given to redundancy; insuring structural stability should localized damage fail components of these trusses.
