Material, species and grade - You must select these from the WoodWorks database file. By default you can select from lumber, MSR lumber, MEL, and proprietary LVL and LSL materials. Using WoodWorks Database Editor, you can add other wall stud materials, or deactivate those you do not use.
The specific gravity found in the species for lumber and in the grade for MEL/MSR materials affects shear design. The species is also used in hold-down capacity determination. The E value found in the grade is used for deflection design.
Stud width and depth - You can select these or enter your own value. Program automatically distinguishes between actual and nominal values similar to WoodWorks Sizer; if you wish to enter an actual size close to a nominal one, then enter e.g. 2.0001. The member dimensions are currently used only for deflection analysis and hold-down design.
No of End Studs - This can be entered at all wall ends and opening ends. Used for the bending component of deflection, design for compression forces, and in determining hold-down and compression force offsets.
Stud spacing – You must select from standard list of spacings from design code tables. If your actual spacing is different, select next largest. Affects out-of-plane sheathing bending design, the choices available for shear design for structural panels, and shear design for gypsum materials. It can be left unknown.
