Timber structures — Determination of characteristic values — Part 5: Mechanical connections

Scope

This document gives methods of determination of characteristic values for a defined population of mechanical connections between timber components, calculated from full scale test values.
It presents methods for the determination of:
a) slip modulus of mechanical connections;
b) characteristic strength of connections subjected to either monotonic or cyclic loads.
Glued connections are excluded from the scope of this document.
NOTE 1 It is assumed that the failure mode is the same for all specimens in the sample.
NOTE 2 When a small number of test results is available, ISO 12122‑6 is used for the determination of the mean and the 5th percentile values.
NOTE 3 Informative commentary to the clauses of this document can be found in Annex A.
