Abstract:
This paper briefly describes the high rise office building designed for the Lot P1 of the Real Madrid Sports City. General characteristics of the urban state plotted out under the Subdivisional Plan for reform and development of the ?Ciudad Deportiva? zoning area are presented. Later the most important data of the building, comprising 5 below grade and 49 above grade storeys, are given. One of the main characteristics of the building design is the creation of a base free of any structural supporting element. All loads are transmitted to the foundation mat through the vertical communications cores. These are disposed laterally in the building plan, at both sides of the central block of office storeys. This design results on an open, transparent lobby, four storeys high, occupying the entire plan of the building. This load path is implemented through specific and robust structural elements which transmit to those lateral communications cores the gravitational loads of the three segments (of 11, 12 and 11 office storeys respectively) in which the central block of the building is divided. Several machine room storeys are integrated between these segments. In the last part of the paper the main technical characteristics of the facilities are briefly described.
