Building Climate – Long-term Measurements to Determine the Effect on the Moisture Gradient in Large-span Timber Structures - P Dietsch, A Gamper, M Merk, S Winter
J Köhler commented that the work was useful and had agreement with his own results. G Schickhofer commented that the work was important and asked about using different kmod factors for different cases. He also asked for comments on the use of reinforcement. P Dietsch responded that this was a balance between scientific knowledge. This was important for large span glulam structures with beams of large widths. The type of reinforcement must consider its suitability in high moisture conditions. S Aicher questioned the conclusion that the timber should be produced to the moisture condition of
use. This point is already in the code but never followed in practice. F Lam asked why correction to low moisture contents were not done as the study had such information. P Dietsch replied that the data was not suitable for this consideration because different types of wood were involved. S Winter stated that in combination with precipitation the erection time of the building was also important.
