The filigree spire of the 116 meter high west tower of Freiburg Minster in Germany was completed around 1330 AD and is an architectural monument of the highest rank. At 45m high and constructed using tracery throughout, the spire is the tallest of its kind ever built. It has survived until the present without major damage or alteration. In 2010, after several flaws in the sandstone were detected, a detailed damage survey and a structural analysis were initiated.
This lecture, based on the award-winning paper, will provide a description of the construction of the spire, the damaged sections that were detected, the material tests and statical calculations undertaken and the implementation of repair measures.
Delegates will hear how:
- A 3D digital model, showing all structural elements, historical alterations and damage, played a particularly important role in understanding the construction and the statical behaviour of the spire
- Wind tunnel measurements and a series of material tests were conducted to ensure a realistic estimation of the stability under wind and seismic load
