Analysis of Tension Tests DVW Reinforced Joints Connected with 35 mm ExpandingTubes. FOREST Project, Part 11

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 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 tubes. This report is part of a set with the statistical analysis of data reported by Elbeck and Werner who tested the dvw reinforced timber joints with expanding tube fasteners. In this case tubes are used which expanded after being mounted in the holes have diameters of 18 and 35 mm. This procedure removes any clearance. The densified veneer wood (dvw) is cross-wise layered.
