Description
Verification of the calculation, due to problems with the glazing
In 1995 and 1996, an approximately 80 m long shopping arcade was roofed in Kirchberg, Luxembourg. The roof consists of pre-stressed membrane panels and so-called glass eyes in between, lens-shaped panels with overhead glazing. The supporting structure of the glass eyes consisted of steel edge and span beams and was attached to the membrane.
Soon after completion, a series of damages became apparent: the individual panes of glass were wandering around on their supporting structure, several panes of glass were destroyed by cracks and the roof's watertightness was extremely poor.
In the course of the damage investigation, Krätzig & Partner was asked whether the damage that had occurred could be attributed solely to the identifiable defects in the execution or also to possible errors in the static calculation.
The FE calculations carried out by Krätzig & Partner using the in-house developed finite element system FEMAS 2000 essentially confirmed the results of the original structural analysis. In addition, the relative displacements between the glass skin and the supporting structure were calculated, which then formed the basis for the renovation construction.
