Abstract
To study the influence of volume on the load carrying capacity of glue d-laminated curved beams and curved pitched beams tests with full-scal e specimens have been carried out. The distribution of the tension str esses perpendicular to the grain was analysed using a finite element c omputer programme. The relationships between the tensile strength and the stressed volume, the shape of the beams and the load conditions is evaluated on the basis of Weibull's theory of brittle fracture. A com parison of the results with the current design proposals in the draft of EUROCODE 5 "Structural timber design code 1987)" indicated higher c haracteristic ultimate tensile stresses and for some cases new stress distribution factors k(dis).
