Fuktinducerade sprickors inverkan på hålkanthållfastheten och hålstyvheten hos dymlingar i gran och björk belastade vinkelrätt mot fiberriktningen / The influence of moisture induced cracks on the embedment strength and stiffness of dowels in spruce and birch loaded perpendicular to the grain

In our modern times, the aim in the construction industry is to lower the environmental impact. This can be done by using materials with a lower impact on the environment. One of these materials is wood. Due to research and increased understanding of wood, it is now possible to construct multiple-storey buildings using wood.Wood is a hygroscopic material, which means that the moisture content will change depending on the humidity and temperature of the surrounding air. Due to the moisture changes in the wood, cracks may appear. These cracks might influence the properties of the wood. The purpose of this thesis is, by conducting EN 383 tests on birch and spruce, to see if the cracks that may appear during moisture changes have an impact the embedment strength, the elastic- and plastic embedment stiffness. The results showed that the cracks do not have a significant impact on the embedment strength or the plastic stiffness, but they do affect the elastic stiffness. From the results the conclusion can be made that when load is applied perpendicular to the grain, the cracks have an influence the elastic embedment stiffness
