Because of the shortage of housing that effects Sweden and the increasing demands for sustainable building new solutions for construction needs to be developed. One solution to this problem is a loadbearing structure made out of crosslaminated timber. This type of material has a high prefabrication factor wich will shorten construction times and it’s environmental freindly. However there is one drawback with this type of loadbearing structure and that is that it’s sensitive to dynamic windforces. Until 1994 it was forbidden by law to build higher than two storeys with a loadbearing timber structure. Therefore the development in this area has fallen behind the development of steel and concrete structures. Because of the many advantages that this type of structure provides the area needs to be explored, developed and the knowledge must be spread to increase the use of crosslaminated timber structures. The purpose of this bachelor thesis is to examine what parameters that effect a buildings dynamic characteristics and how tall it is possible to build with the chosen dimension of the loadbearing structure.
