Description

1.1 The purpose of this Engineering Practice is to establish guidelines for designing and calculating allowable bending properties of mechanically laminated wood assemblies used as structural members.

1.2 The scope of this Engineering Practice is limited to mechanically laminated assemblies with three or four wood laminations that have the following characteristics:

• 1.2.1 The actual thickness of each lamination is between 38 and 51 mm (1.5 and 2.0 in.).
• 1.2.2 All laminations have the same depth (face width), d.
• 1.2.3 Faces of adjacent laminations are in contact.
• 1.2.4 The centroid of each lamination is located on the centroidal axis of the assembly (axis Y-Y in Figure 1a), that is, no laminations are offset.
• 1.2.5 Concentrated loads are distributed to the individual laminations by a load distributing element.
• 1.2.6 All laminations are of the same grade and species of lumber or structural composite lumber.
• 1.2.7 There is no more than one common end joint per lamination within a splice region.
