Our timber research at Cambridge University continues with a full size rib slab test completed to failure.

The test focused on the end support behaviour of a large 10.5m by 2.4m CLT slab reinforced with glulam ribs. The glulam ribs are stopped short of the bearing to ease fabrication and on site installation. This end detail also aids building services distribution.

The lab test slab managed to take 24t before a glulam beam de-lamination failure occurred with a load bang.
