Important results from the project
The aim of the project was to develop knowledge and models to calculate the dynamic performance, in serviceability limit states, for tall timber buildings. Within the project, dynamic properties of eight tall timber buildings, of which one in Sweden, were measured using shakers and accelerometers. This has provided a measure of how the buildings behave under wind load and provided input for how future tall timber buildings can be designed. Calculation models have been developed which were used to study which parts of the building are important to include in the calculation model.
Expected long term effects
The project has contributed with validated damping values for tall timber buildings, which was previously missing in the European design standards. The project has also contributed knowledge about which parts of the building are important to include in a calculation model so that it can predict the dynamic properties of the finished building. The results from the project have been shared with designers and architects via conference contributions, peer-review articles, but also via several lectures for working engineers and via posts on LinkedIn and ResearchGate.
Approach and implementation
The project was mainly carried out in accordance with the project plan, however, restrictions linked to Corona meant that the work had to be partially rescheduled. The plan, which meant that the University of Exeter would carry out full-scale measurements in Sweden, had to be changed to that the measurements had to be carried out under the leadership of LNU with newly acquired equipment. In many cases, the part of the project linked to calculation models had to be carried out before the full-scale measurements and then validated against these, but nevertheless showed promising results.
