Guidance on designing reinforced concrete retaining walls

Q. I am interested in documents that apply to designing a reinforced concrete retaining wall. What is SP-17 and does it provide more required information that goes along with the code requirements?

 

A. SP-17 is a document that provides additional explanatory text, design examples that illustrate ACI 318 code provisions, and design aids that assist with the use of ACI 318. There are no additional requirements in SP-17 that are not in ACI 318. Note that Chapter 12 of SP-17 specifically covers retaining walls.
