Production of radiata glulam for Olympic facilities

Glulam members for the construction of buildings to be used for the Olympics 2000 games in Sydney, were specified as F11 grade. This requires a characteristic bending strength in the outer laminations of 33 MPa and a modulus of elasticity of 10.5 GPa. Proof tests on the initial production showed it to be inadequate. This paper describes the material selection, proof testing, and other measures necessary to provide the required performance.
