Abstract
The erection of ancient roof structures was based on the experience, tradition
and the courage of their constructors instead of a structural analysis. A realistic model
requires the consideration of the spatial load-bearing behaviour, as well as the flexibili-
ties and the eccentricities of carpentry joints. However, the utilization ratios of roof
structures yield high values, so no meaningful statement about the load-bearing capa-
city of these structures can be made. By using the "Grazer Dachstuhl" as an example,
changes of the utilization ratios as a consequence resulting from the consideration of
the capacity of the roof battens are pointed out. In the beginning, some theoretical
background on the load-bearing capacity of roof battens is presented. This is followed
by a report of some structural tests and the documentation of a model calculation.
Based on the findings of the analysis of ancient roof structures, a protecting
repair-concept using wood-based panels will be developed. This integral structure com-
prises the improvement of the rafter roof, a strengthening of the rafters themselves and
their bases and an in plane-bracing of the roof. Additionally, this concept is characteri-
sed by economical, constructural and building-physical advantages.
