Description

This report describes the experimental testing of six full-size nailed moment-resisting gusset connections between glulam timber members when subjected to the 60 minutes (min) standard time temperature conditions.

The parameters examined included different gusset types, different protection methods, beams of two depths, and two levels of applied lead. This report also describes the experimental testing of four unloaded gusseted glulam specimens protected with a single layer of the 'control' board subjected to the 60 min standard time temperature conditions.

These tests were carried out in a pilot furnace to determine the time temperature characteristics of the components beneath the protection, to enable a comparative test method to be developed.
