This 2-hour online course is part 2 of a two part series on analyzing and designing cantilever type retaining wall structures. The purpose of these walls is to hold back or support soil banks, and other storage materials such as coal, gravel, etc. at a higher elevation on one side of the wall than the other side. Part 1 described the process of determining the stability of this type of structure, while this part is involved with determining the internal forces and stresses of the cantilever retaining structure and selecting sizes and spacing of steel reinforcing and dimensions of a reinforced concrete cantilever retaining wall. Appropriate sections and equations of the American Concrete Institute's ACI318 (latest edition) will be referenced in the design process.

Due to the extensive amount of math used in this course, it is presented in a Word document format which must be downloaded by the student. There is a test at the end of this course.

After the completion of this course, you will be able to:

• Calculate shear and bending moments at critical sections in a cantilever retaining wall
• Determine the size and spacing and location of steel reinforcing for the stem and footing parts of the cantilever retaining wall
• Determine the required 28 day compressive strength of the concrete, the thickness of the stem and footing parts of the cantilever retaining wall
• Specify backfill and drainage requirements for a cantilever retaining wall
