Comparison of theoretical and experimental determination of deformations of timber façade elements against wind load

The current practice is that the deformations of timber façade elements are determined by testing, or they are limited by prescribing dimensions in a very conservative way. To use generic calculation models, suitable for almost all types of windows, approximations deviating from the actual behaviour have to be done. This paper investigates if a calculation method can predict the results from laboratory test with the required accuracy. For that purpose 29 façade elements were tested. Results showed that the calculation method gives a good, slightly conservative prediction for the laboratory tests. As a result, especially for specific project-made windows in small series, the costly laboratory tests can be replaced by calculation.     «
