For structural engineers, the two most important design criteria are utility andsafety. It is about making sure that a structural component is reliable enough not toendanger any of a building's users, while at the same time being as sustainable andefficiently designed as possible. In other words, an element must be safe enough towithstand the improbability and sufficiently cheap to be relevant for the design.Considering this, using a material such as wood instead of metal may prove to be asustainable alternative for certain building components.Timber can be designed to sustain high temperatures and fire; it has a high strengthrelative to its weight and is naturally produced. Furthermore, an engineered woodproduct such as birch plywood has proven very strong in structural applications,especially when glued. Therefore, birch plywood has great potential as a reliablematerial in structural components. In this work, a total of 24 specimens with birchplywood connections were tested experimentally.The specimens were designed to enforce stress states that would occur in actualtrusses. Additionally, Specimens were assembled with two different connectionmethods, one being a dowel-type connection and the other being a glued-type. Eachtype of connection was tested in both tension and compression, with a total of threerepetitions each. For the glued-type specimens, birch plywood plates wereinvestigated in three different angles to the face grain; 0°, 5° and 15°. Theload-displacement relationships and the failure modes are of specific interest in thisthesis.Test results showed that failure modes were semi-brittle and distinct, and the testsshowed that glued-type connections withstood 37% higher loads than dowelledtypes. Specimens might withstand even higher loads if gluing were performed in amore controlled environment. The load-to-face-grain angle of plywood also had asignificant impact on the capacity of connections. For the 0°-specimens with gluedconnections tested in compression, no failures occurred in the plywood, and testsreached loads as high as 82 kN. Calculations were made estimating the load capacityas high as 95 kN, but possibly a more realistic approximation would be 85 kN. Thiswould imply that the 0°-specimens are around 20% stronger than the 15°-specimensand approximately 17,7% stronger than the 5°-specimens tested in compression.Birch plywood is promising to be used in connections of timber structures whereplates transfer forces between structural elements.
