Abstract
This paper presents an experimental analysis of timber-framed wall elements
with openings, coated with single fibre-plaster boards fastened to a timber frame.
The present study is a continuation of the research work realized in recent years
in the reinforcement of prefabricated timber-framed wall elements without any
openings. Of course, in an apartment building, many walls may have one or
more openings for functional reasons, doors or windows, where a concentration
of the tensile stresses around the corners appears and consequently results in an
essential decrease of the wall’s bearing capacity and the horizontal stiffness. We
tested three groups of test samples in order to carry out an appropriate research
about the influence of the area of opening on the stiffness and load-carrying
capacity of the panels. The measured values for the non-opening test samples
were taken from the previous research work and were compared with the
measured values of the timber-framed wall elements with openings.
Keywords: timber, frame walls, openings, fibre-plaster boards, experiments.
1 Introduction
There is an increasing tendency worldwide to build multi-level prefabricated
timber structures with timber-framed walls as the main bearing capacity
elements. As the treated timber-framed wall elements are a composite system
composed of a timber frame and fibre-plaster coating boards that are connected
to the timber frame by mechanical fasteners, it is possible to assure with suitable
boundary conditions a composite behaviour between the boards and the timber
frame along the whole element and consequently to increase the wall bearing
capacity. Because the tensile strength of the boards is smaller than the strength of
the timber frame, the boards present the weaker part of the treated composite
system. The present study is a continuation of the research work realized in
