Spacing of Finger Joints

Research shows that end joints are a common point of weakness in glulam members used as beams and tension members. Because the use of short lamination segments simply increases the probability of a low strength end joint lying in a highly stressed region, it is crucial that they be limited in number.

Beams with relatively few end joints in the outer tension laminations tend to be stronger than beams with a large number of end joints in the outer tension laminations.

The critical laminations are in the outer 0.15 D tension laminations in beams. In tension members all laminations are equally critical.

This is one of the unique characteristics that we at Laminated Beams Ltd specifically focus on when engineering our product.
