“…Numerical results showed that the wall elements with OSB (Oriented strand board) sheathing board have higher racking resistance than walls with fibre-plaster boards irrespective of the spacing between fasteners, and they are recommended for use in tall timber-framed buildings located in very windy or earthquakeprone areas. An experimental analysis on the influence of fastener spacing for fibre-plaster board has been presented in [23] for single fibre-plaster sheathing boards, and in [24] for double fibre-plaster boards. Results for different fastener spacings of 37.5 mm, 75 mm and 150 mm showed that the bending stiffness of a timber-framed wall strongly depends on the fastener spacing s and is higher the smaller the distance between staples.…”

a b s t r a c tThis paper presents mathematical modelling of timber-framed wall where a braced frame with one fictive diagonal is used. The model is suitable for analysis of lateral loads on the structure. Its advantage compared to other models is its simplicity, the fact that it is easy to use in practise, and its suitability for use with simpler and cheaper programs for static and dynamic analysis. Further numerical calculations were performed, which showed good approximation with experimental studies and with the finite element method. The Tower 6 program for static and dynamic analysis has been used to model timber-framed walls. Appropriate stiffness of timber-framed wall is obtained by varying the cross-section of the fictive diagonal. Because the cross-section of the fictive diagonal is directly connected to the analytical calculation of the stiffness of the timber-framed wall, this model is also able to factor in different spacing distance, different sheathing boards, the appearance of tensile cracks in a sheathing board, as well as walls with glazing or openings.

“…Since the wall element is treated as a composite system, the wall's behaviour strongly depends on the fasteners disposition, which is already experimentally tested on wall elements with doubled FPB on each side [11]. Therefore, it is interesting to analyse a fully new possible technological solution when the FPB are not mechanically connected to the timber frame, but they are glued to the timber studs and girders.…”

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.
