INFLUENCE OF EDGE BONDING AND GAPS BETWEEN LAMINAE OF CLT ON PULL-OUT PROPERTIES OF LSB

Parallel to the grain direction (Part 1)

Abstract

An influence of edge bonding between laminae, edge gaps between laminae without edge bonding, and edge distance from LSB to egde of a lamina, on pull-out properties of LSB joint embedded into CLT parallel to the grain direction was investigated and confirmed following characteristics.
1. Edge bonding was no effect on pull-out properties.
2. Pull-out properties of LSB embedded into a gap decreased with increasing width of the gap.
3. The edge distance was no effect on pull-out properties, if it is more than 0.7 times of a top thread diameter of LSB or the gaps is below 0.5 mm.
