The structure of cooling towers in Hambung, Germany, had to be recalculated to find possible capacity reserves due to current codes.
The hyperbolic cooling towers are made up of a regular dodecagonal space trusses without internal bracing. Inside, the steel framework is covered with cladding made of fiber concrete corrugated plates. The steel structure is supported by a circular stake‑beam construction made of reinforced concrete.
At the top of the tower, a surrounding gallery is used as a stiffening ring. Beams at distances of about 2 m are designed as parabolic girders to stiffen the structure.
Prof. Dr.‑Ing. H. Kramer, Dipl.‑Ing. F. Albrecht and Dipl.‑Ing. (TU) Leif Lorenzen from engineering office KramerAlbrecht, the customer of Dlubal Software, were responsible for the inventory review and expert’s report towards the state of construction of the eastern and western cooling towers.
They evaluated and documented the condition of all structural elements, its connections as well as the present condition of the anticorossive coating. On the basis of the acquired information, the level of necessary renovation was determined.
