Abstract
This paper provides an experimental analysis of timber-framed walls, coated
with carbon fibre-reinforced polymers (CFRP) strengthened fibre-plaster boards.
The presented wall elements are usually used as main bearing capacity elements
in the construction of prefabricated multi-level timber residential buildings.
Since the tensile strength of fibre-plaster sheathing boards (FPB) is
approximately 10 times lower than the compressive strength, cracks in the tensile
diagonal board’s direction usually appear in tall buildings in heavy seismic areas.
Therefore, in such cases, it is convenient to strengthen boards with high-strength
materials in order to gain a higher capacity. It has been experimentally shown
that the inclusion of CFRP diagonal strip reinforcement on the load-carrying
capacity can be quite high and that it is maximized when the carbon strips are
connected to the timber frame. On the other hand, the ductility itself was not
significantly improved. Finally, a numerical study for FPB, which are glued to
the timber frame and strengthened with CFRP strips, is preliminary presented for
possible new technological solutions for treated wall elements in heavy seismic
areas in the future.

1 Introduction
There is an increasing tendency worldwide towards building multi-level
prefabricated timber structures. It is clear to competitive fields of building that
today’s timber frame building is extremely highly valued and it is capable of
