EXAMPLE:

Determine the tie-wire spacing (in inches) if the ULW is 1,250 pounds per linear foot and

you are using No. 9 steel wire gage.

by comparing the results from steps 11 and 12 and then using the smaller of the two tie-wire

spacings as the maximum tie-wire spacing.

EXAMPLE:

Determine the maximum tie-wire spacing value by comparing the following measurements:

Tie-wire spacing based on wale size = 24 inches.

Tie-wire spacing based on wire strength = 20 inches.

Use the smaller tie-wire spacing of 20 inches for the maximum tie-wire spacing.

covered in step 13. The solution to this problem is found at the end of the lesson. Determine

the maximum tie-wire spacing value by comparing the following measurements:

Tie-wire spacing based on wale size = 26 inches.

Tie-wire spacing based on wire strength = 16 inches.

Use the smaller tie-wire spacing of 16 inches for the maximum tie-wire spacing.

maximum stud spacing (step 7) and the maximum tie-wire spacing (step 13), it is time to

compare the two. The correct location of your ties must be determined to ensure that the form

design has the proper strength.
