D1.G.3.1 Explanation of Input Commands and Parameters
Specify PARAMETER and then CODE TIMBER to start TIMBER DESIGN before specifying the input parameters. The user must provide the timber grade (GLULAM GRADE) for each member he intends to design. The parameters can be specified for all or specified list of members. If a parameter is not specified, the default value is assigned to it. See following INPUT PARAMETERS LIST TABLE for description and default values of the parameters.
D1.G.3.2 Glulam Grade and Allowable Stresses from Table
The allowable stresses for GLULAM members are read in from Table-1 and Table-2 of AITC for design values for Structural Glued Laminated Timber. The structural members are to be specified in the following manner:
AITC Table-1 glulam members
AITC Table-2 glulam members
For TABLE-2 members, the applicable stress values are selected based on the depth and the number of laminations.
