Abstract
The functionalites of new concreting methods used for constructing 50m high steel composite columns with high performance concrete, are discussed. The new concreting method involving filling of concrete under pressure through inlet connecting branches placed at the steel section with the concrete was used to support 50m high steel composite columns which was supporting the vertical load of Berlin central station. The bottom access technique and concrete having high flowing property was used to distribute compaction to avoid the entry of air into the concrete. Hollow section columns of 500mm×500mm dimension and compression members of the frameworks (post and middle chords (600mm×600mm) and top chord (1200mm×600mm) were designed as composite columns. The exterior and interior columns of the Link feet, pylon of the lattice girders, and bottom chords of the lattice girders were concreted after erection with 1600m 3 concrete.
