Haukilahti Water Tower

In this project the original concrete dome structure was replaced by new post-tensioned spherical concrete dome. Post tensioning was needed in a circumferential direction of the dome, in order to counteract support reactions and limit tensile stresses in concrete.

       

 

In this project the domed roof of this functioning water tower was replaced by new post-tensioned spherical concrete dome. Post tensioning was needed in a circumferential direction of the dome in order to counteract support reactions and limit tensile stresses in concrete.

Due to historic reasons the project needed extra care and dedications as the external parts of the dome are prone to buckling. Stability analysis was made using RFEM's advanced analysis modules as described below.

 RFEM Advantage:

 Modelling ease due to RFEM's advanced geometric modelling capability including the facility for making various types of curved shaped shell panels.

 Flawless meshing of spherical surface saved engineer extra time that would otherwise be used to fix meshing problems commonly encountered in other software.

 3rd-Order geometrically non-linear analysis while accounting for cracking, shrinkage and creep respectively. Consideration of such long-term degredation of concrete in stability analysis turned out to be extremely useful tool in the investigation of older structures. For the Finnish enginner on record there was no other alternative software capable of incorporating such effects.
