ISO 12122-5:2018 PDF Download

ISO 12122-5:2018 is a standard that provides methods for determining the characteristic values of mechanical connections in timber structures. The characteristic values are derived from full scale test values and are used to assess the performance of these connections under various load conditions.

The standard covers two specific aspects of mechanical connections in timber structures. Firstly, it outlines methods for determining the slip modulus of these connections, which is a measure of the resistance to relative movement between timber components. Secondly, it provides techniques for determining the characteristic strength of connections when subjected to either monotonic or cyclic loads.

It is important to note that this standard excludes glued connections from its scope. Additionally, it assumes that the failure mode is the same for all specimens in the sample, allowing for a consistent assessment of the characteristic values.

In cases where a small number of test results are available, ISO 12122-6 is referenced for the determination of mean and 5th percentile values. Informative commentary to the clauses of this standard can be found in Annex A, providing additional guidance and clarification.
