Abstract
This paper provides numerical analysis of the influence of fastener disposition on
the behaviour of timber-framed walls, coated with single wood-based sheathing
boards fastened to a timber frame. As the walls under a horizontal load actually
behave like a deep composite beam, the disposition of the fasteners is very
important and directly influences the bearing capacity, as well as the stiffness of
the wall. This analysis is done on a special semi-analytical mathematical model
that is based on a composite cantilever using the so-called \“γ-method” in
dependence of any possible spacing between the fasteners. It is demonstrated
that the lateral stresses acting on one fastener usually reach the yielding point
before any crack appears in the sheathing boards and the normal stresses in the
timber frame are rather under the characteristic timber strength for any spacing
between the fasteners. The obtained numerical results are supported with the
measured ones from our previous experimental study.
Keywords: timber structures, walls, oriented strand boards, fasteners, numerical

1 Introduction
Timber is commonly associated with lightweight construction, although it is
ubiquitous as a building material. Timber construction is an important part of the
infrastructure in a number of areas around the world. Well-built timber structures
usually maintain good performance under the influence of wind and especially
earthquake forces. Nowadays, there are the strongest arguments for building
timber frame buildings. Brand new and improved features, introduced in the
early 1980s, brought about the expansion of timber frame buildings all over the
