This book provides an experimental analysis of timber-framed walls, coated with single sheathing boards fastened to a timber frame, usually used as main bearing capacity elements in the construction of prefabricated timber structures. As designers or producers usually find themselves in an important dilemma which sheathing board is better to use according to the known height and location of the building, the aim of the presented analysis is comparison of the results measured on test samples covered either with fibre-plaster or wood-based sheathing boards. Therefore, the presented conclusions, supported by the measured results, give some important indications in behaviour of the timber-frame wall elements covered with different sheathing boards according to the known horizontal load and consequently, could give some important recommendations in designing of tall timber-frame buildings located on heavy windy or seismic area.

Disertacija obravanava vpliv togosti veznih sredstev in vpliv obložnih plošč na nosilnost lesenih okvirnih stenskih elementov pod vplivom horizontalne sile. Okvirni stenski element predstavlja sovprežno konstrukcijo, sestavljeno iz lesenega okvirja in obložnih plošč, ki so na okvir pritrjene z mehanskimi veznimi sredstvi - sponkami. Vpliv sponk smo raziskovali z različnimi razdaljami med sponkami, in sicer na preizkušancih z razdaljo med sponkami s=3,75 cm, s=7,50 cm in s=15,00 cm. Vpliv obložnih plošč smo raziskovali z različnimi vrstami obložnih plošč, in sicer z enojno mavčno - vlakneno oblogo, z dvojno mavčno - vlakneno oblogo in z oblogo z usmerjenim iverjem. Raziskave smo izvedli eksperimentalno, analitično in numerično (MKE). Analitični, in še posebej rezultati numeričnega MKE modela, se dobro ujemajo z ekperimentalnimi meritvami. Razdalje med sponkami in različne vrste obložnih plošč imajo pomemben vpliv na raziskovalno silo ob pojavu prve razpoke obložne plošče, silo porušitve, pomik konzolnega dela panelne stene in na zdrs v nateznem in tlačnem območju priključne ravnine med lesenim okvirjem in obložno ploščo, kakor tudi na upogibno in strižno togost panelnih sten.
