Design, Calculation and Construction Work of a Prestressed Composite Construction to Support the Façade Columns of a High-rise Building

The publication describes the design, the structural analysis and the execution of two similar, high‐rise residential buildings in Frankfurt on the Main. The high‐rise buildings have 15 respectively 17 floors above ground. The socle of the high‐rise buildings contain the entrance (ground floor) and the building technology (1^st and 2^nd floor). The other 12 respectively 14 floors serve only residential purposes. The residential floors of the buildings protrude over the three‐storey high socle. The façade columns of the high‐rise buildings are existing only in the residential floors. Their load must be transferred to the socle. This load transfer is made possible by the all‐around cantilevered, prestressed composite construction above the socle.
