Analysis of Variation of In Plane Tension Tests. Densified Veneer Wood FORESTProject, Part 5

摘要

Preliminary tests with densified veneer wood (dvw) locally glued to the surfaceof the timber members of joints showed an appreciable improvement of the joint strength stiffness and ductility capacity. As the improvement proved to be interesting for industry further research was initiated. The joints fit for this reinforcement are mainly build-up joints as applied in trusses and portal frames. The joint members are connected by means of mechanical fasteners like dowel type fasteners. Densified veneer wood (dvw) for this application has been cross-wise layered. As the old test data is limited with respect to the number of tests carried out and the properties investigated the intention is to perform additional tests that give adequate information required for structured application of the dvw. Therefore the in plane tension and compression strength as well as the embedding strength are determined. The test reports contain all relevant data of this matter. The report is part of a set with the statistical analysis of all test data.
