Timber property assumptions
The engineer shall verify that the properties of the selected grades are those that are characteristic of the material, are obtained from up-to-date manufacturer’s data and are applicable to the analysis model. Analysis Modification Factors must also be confirmed to be correct.
Head Code Eurocode
The following assumptions have been made:
-
Loading will be perpendicular to the wide faces of the laminations (bending about the major axis).
- Moisture content of the sections will be less than 15% - analysis modification factors may need to be applied if this is not the case.
- The glulam grade being used complies with the characteristic properties outlined in BS EN 14080:2013.
- The engineer has verified that the Eanalysis value of the member is suitable for the particular application.
- The section and strength class are compatible.
Head Code ACI/AISC
The following assumptions have been made:
-
The moisture content of the structural composite lumber or glulam section is less than 16% and the temperature remains below 100°F - analysis modification factors may need to be applied if this is not the case.
- The glulam section will be loaded perpendicular to the wide faces of the laminations (bending about the x-x axis).
- The glulam grade being used complies with the characteristic properties outlined in AWC NDS supplement 2018.
- The engineer has verified that the Eanalysis value of the member is suitable for the particular application.
- The section and strength class are compatible.
