EXAMPLE:
Find the maximum wale spacing if the uniform load is 1,560 pounds per linear foot and the
studs are 2 x 6 inches.
23 inches
Problem 13. Work the following problem to see how well you understand the concept
covered in step 9. The solution to this problem is found at the end of the lesson. Find the
maximum wale spacing if the uniform load is 581 pounds per linear foot and the studs are 2 x
4 inches.

Step 10. Determine the uniform load on a wale (ULW). Determine the ULW by multiplying
the maximum concrete pressure (step 6) by the maximum wale spacing (step 9). The ULW is
measured in pounds per linear foot. Compute as follows:
maximum concrete pressure (psf) x maximum wale spacing (in)
ULW (lb/lin ft) =
(11)
12 (in/ft)
Use the actual concrete pressure, not the adjusted value that was used to obtain the
wale spacing (step 9).
Carry out the answer to two decimal places.
EXAMPLE:
Determine the ULW if the maximum concrete pressure is 550 psf and the maximum wale
spacing is 20 inches.
550 x 20

Problem 14. Work the following problem to see how well you understand the concept
covered in step 10. The solution to this problem is found at the end of the lesson. Determine
the ULW if the maximum concrete pressure is 350 psf and the maximum wale spacing is 26
inches.

Step 11. Determine the tie-wire spacing based on the wale size. In step 13, you will compare
the results of steps 11 and 12 to select the maximum allowable tie-wire spacing. Determine
the tie-wire spacing based on the wale size by using Table 4 and the following procedures.
The sizes at the top of the table refer to the wale material being used. The table is divided
into two halves--single-wale members are located on the left and double-wale members are
located on the right.
