Reconstruction and Revitalization of Peter Behrens' 'Berolinahaus'(at Alexanderplatz 1 in the center of Berlin – Germany)

摘要

During a reconstruction phase of Alexanderplatz in the center of Berlin in the early 1930s, thefamous architect Peter Behrens designed the building "Berolinahaus", which till now gives theplace its unique appearance and is therefore a listed building. The high-rise building has areinforced concrete skeleton-frame structure, which was really innovative and one of the first at allat the time of its construction.Now a new concept with retail stores in the lower four floors and office space in the upper floorswas created to revive the "Berolinahaus".The method of shifting loads from the existing static system to the new construction in the lowerlevels, while the upper four floors are still intact, is presented. The complexity of the design and itsapplication, while minimizing deformations, time and costs, is shown by ambitious constructionsbased on a structural analysis in special construction phases.
