Abstract

The reconstruction of the destroyed Frauenkirche in Dresden started in 1993. To take up the circumferential tensile forces acting in the main cupola, the engineer decided to incorporate 6 steel stressing anchors which, once stressed, apply a low pretension to the sandstone. The cupola of the old church had developed severe cracks which were to be avoided in the reconstruction. This special task required a specifically designed stressing equipment and a special stressing technology.
