Votivkirche Wien

Structural analysis for the scaffolding above the crossing.

As part of the renovation work on Vienna’s Votive Church, we carried out a detailed calculation of the three-dimensional load-bearing structure. The aim was to ensure the safety of scaffolding erected above the intersection of the nave and transept. This scaffolding rests on an existing steel supporting structure consisting of under-tensioned roof girders that converge in a steel girder grid at the ridge.

The steel girder grid in turn forms the basis for the supporting structure of the crossing tower. This is made up of tapered T-shaped steel fins. Our task was to analyze and evaluate the loads from the external scaffolding and their influence on the supporting structure and the Ixen girders underneath.

Restoration and stabilization of the canopies

Following the successful structural analysis, we continued with the restoration work and turned our attention to the severely damaged canopies. Many of these ornate elements exhibited massive cracks caused by material stresses despite the lead-poured steel profile closures.

To repair the canopies, the superstructures were removed, the cracks were injected with synthetic resin and new console reinforcements made of glass or carbon fiber rods were glued into drilled holes. These measures served to anchor the main stones to the rear and secure the historical substance in the long term. With precise structural analyses and innovation solutions, we are helping to preserve the Votive Church for future generations.
