Expand the template from Prob. 12.1 to handle laterally loaded toenail connections in addition to conventional shear connections. Input is to essentially remain the same as Prob. 12.1, but some method of distinguishing between a toenail and a nail not driven as a toenail is required.

One approach is to leave the thickness of the side member blank (i.e.,
 = 0) to indicate a toenail connection. The spreadsheet would then evaluate
 for the toenail using the geometry.

Prob. 12.1

Use spreadsheet or programming software to set up a template for the solution of the yield limit equations for a laterally loaded nail. Consider a single-shear wood-to-wood connection, using the following variables for input: Nail diameter D Nail length l Thickness of side member
 Specific gravity of the side member
 Thickness of main member tm Specific gravity of main member
 The template is to do the following:

a. Compute the dowel bearing strength for the side and main members
 and
.

b. Determine the dowel bearing length of the nail in the main member
.

c. Evaluate the coefficients for use in the yield limit equations.

d. Solve the six yield limit equations and select the smallest value as the reference design value Z.
