Topic Objective:
The objective of this set of on-line notes is to provide you with a simple, albiet conservative, technique for analyzing and designing walls in combined bending and compression. This topic relies heavily on the information found in the previous bending and axial topics. Combined bending plus compression is the most common load condition for walls.
Topic Directions:
One class day is devoted to this topic. To satisfactorily complete this topic, you must:
- Study the 2 sets of on-line notes.
- Complete the reading assignment.
- Come to class prepared to discuss this topic.
- Complete the homework assignment.

Problem Assignment:
- A 20' high partially grouted wall is constructed with 8" CMU blocks. Assume pin connections at the top and bottom of the wall. f `m = 1500 psi and the vertical reinforcement is #5 @ 32" o.c., Grade 60. A roof load of 240 lb/ft acts through a ledger with e = 6.3 inches. Is this wall adequate?
