1. In retrospect, it probably would not have been necessary to check all three criteria at all locations. With experience, a designer could realize that the location with highest wind moment would govern, and could therefore check only the mid-height of the wall.
2. The addition of wind load to the example of Sec. 5.2.4, to produce the example of Sec. 5.2.5, changes the critical location from just under the roof, to the mid-height of the simply supported section of the wall. The wind load of 25 lb/ft2 in example of 5.2.5
produces maximum tensile stresses above the allowable values for ungrouted masonry, and makes it necessary to grout the wall, thicken it, or reinforce it.
