Tiivistelmä
Timber gains more awareness in the construction industry, due to its sustainable characteristic. In addition, with the development of engineered wood products the limitations of sawn timber can be overcome and increase applications for load bearing timber elements in buildings.
Therefore, the thesis deals with the use of sawn timber, glue laminated timber and laminated veneer lumber for load bearing beams. With the creation of a selection tool, designers are supported at determining efficiently suitable timber products for specific projects in Finland.
A survey is conducted among Finnish timber product suppliers, to highlight dissimilarities and similarities of the considered materials and pinpoint common dimensions. Additionally, the current sales as well as possible developments for future timber constructions are examined. To ensure a stable design of proposed beams calculations applied in SFS-EN 1995-1-1:2004 are taken into account.
By combining results of the survey and regulations given in SFS-EN 1995-1-1:2004, the selection tool is created in Excel in form of a table. It evaluates the load bearing capacity for the most common cross section dimensions of timber beams, depending on different design requirements and results in a recommendation for suitable products.
