Estimate the shrinkage that will occur in a four-story wood-frame wall that uses Hem-Fir framing lumber. Consider a decrease in moisture content from 15 to 8 percent. Framing is typical platform construction with 2 x 12 floor joints resting on bearing walls. Wall framing is conventional 2 X studs with a typical single 2 x bottom plate and double 2 x top plates. See Fig. 4.7.
