The used and developed basics of the project are the climate data of Switzerland, measurements of climate and moisture content in load bearing cross-sections obtained from long-term monitoring campaigns, and the developed numerical model to calculate the moisture diffusion, the dimensional change and the resulting moisture induced stresses. In addition, required material parameters were determined in small laboratory series that improve and support measurements made during the monitoring campaigns. The climatic data and wood moisture content values obtained within the long-term measurement were classified according to the building type and visualized accordingly for the practicing engineers. Published data from other research institutes were also included into the analyses where possible. In addition to the general information on moisture content as listed in the SIA 265:2012, useable climate profiles are now available for a variety of building types and for bridges, too. Specific questions concerning bridges that still led to discussion and unanswered questions were considered and evaluated. The application of a quality assurance monitoring method and system is described. The created numerical model was validated and used in parameter studies to assess the effects of cross-section size or the impact of the construction period. realistic climate profiles found in ice rinks, riding halls and bridges were used to calculate dimensional changes and moisture induced stresses.
