20.500.12556/RUL-188005 Mehanske lastnosti moznikov iz bukovega lesa diplomsko delo Mechanical properties of beech wood dowels V okviru te diplomske naloge smo izvedli upogibni preizkus in test vtisne trdnosti na moznikih iz bukovega lesa. Pri izvedbi smo se navezovali predvsem na navodila standardov in ostalih virov, v katerih so bile izvedene podobne preiskave. Teste smo izvedli na moznikih, ki smo jih izdelali s struženjem ter na kupljenih moznikih. Poleg tega smo za izdelavo kvadrov za preizkus vtisne trdnosti uporabili tako smrekov kot bukov les. Rezultati preiskav so nam omogočili, da določimo količine kot so maksimalni upogibni moment, upogibna trdnost moznika, modul elastičnosti pri upogibu, vtisna trdnost in togost pri vtiskanju. Nekatere od teh količin so pomembne predvsem, ker se uporabljajo v enačbah za določanje strižne odpornosti veznih sredstev v lesenih konstrukcijah; poleg tega pa nam omogočajo celosten vpogled v obnašanje lesenih veznih sredstev. Rezultate preiskav smo statistično analizirali in preverili, kako se ti razlikujejo pri različnih skupinah preizkušancev. Zanimale so nas razlike v obnašanju izdelanih in kupljenih moznikov ter različnih vrst lesa pri testu vtisne trdnosti. Poleg tega smo preverili, kako gostota osnovnega materiala in veznega sredstva vplivata na omenjene količine. As a part of this thesis we performed the bending and embedment test on beech dowels. The tests were carried out in accordance with relevant standards and other sources that dealt with similar experiments. Dowels made by turning and purchased dowels were used in both tests. In addition, spruce and beech wood were used to manufacture the timber members for the embedment strength tests. The results of the experiments enabled us to determine parameters such as the maximum bending moment, bending strength, modulus of elasticity for bending, embedment strength and foundation modulus. Some of those parameters are particularly important because of their use in the determination of shear strenght of wooden dowels. Furthermore, they provide insight into the behaviour of wooden dowels in timber structures. The test results were statistically analysed to assess the differences between the various groups of specimens. We were particularly interested in differences in results manufactured and commercially purchased dowels, as well as in the effect of different timber species in the embedment strength tests. In addition, we examined how the density of the base material and the dowel affects the mentioned parameters. diplomske naloge gradbeništvo moznik bukev upogib vtisk upogibna trdnost modul elastičnosti vtisna trdnost graduation thesis civil engineering dowel beech bending embedment bending strength modulus of elasticity embedment strength true false false M.
