Soldier pile retaining wall using a waler with off-centered tieback
Soldier pile retaining wall using a waler with off-centered tieback
(OP)
Consider a soldier pile retaining wall that uses a waler with a single tieback to support 2 adjacent piles. Traditionally such a tieback would be centered between the piles. However, due to project constraints the tieback needs to be installed off-centered. For example, with a 6ft soldier pile spacing the tie back is installed 2ft from the left pile and thus 4ft from the right pile. How will this change the loading to the tieback. To maintain static equilibrium in the design case described, I calculate that the tieback force will increase by 50% as compared to a tieback centered between piles. Can someone confirm or correct me?

Example: If you need 100 kips per each soldier beam, that would be a 200 kip tieback centered on the wale, 3' off each soldier beam. If you move the tieback over 1 foot to be 2' off one beam and 4' off the other, you need a 300 kip tieback design load (300 / 200 = 150%). Then, 100 kips will go to one soldier beam but 200 kips will go to the other.

See the attached calc for the tieback load and forces applied to each soldier beam.
