Glued-in rods in beech laminated veneer lumber

Beech laminated veneer lumber is a new engineered wood product with superior mechanical properties and high density. In order to take advantage of this superior mechanical performance in the case of connections with glued-in rods a series of pull compression tests with different angles to the grain have been performed applying both polyurethane and epoxy resin as adhesives. No influence of the grain angle on the load carrying capacity could be found. In addition, a survey on design rules and their acceptance in practice has been carried out, showing a clear need for further standardization.
