Abstract
Decay and drying cracks affect the strength of historic timber structures. Because
of the traditional timber dimensions used, drying cracks are often large,
decreasing the effective cross section of members. Deterioration can also be
caused by biological decay, depending on wood species, climatic conditions,
structural detailing, etc. Decay can affect the load carrying capacity, having
considerable economic and cultural consequences. However, when the decay is
no longer active and the damage is limited, repair is not always necessary. When
the reliability of the structure is above a certain minimum acceptance level, it is
still able to fulfil its task and can be maintained in the original state as much as
possible. A method to determine the safety of deteriorated structures is lifetime
modelling using d
