F i g u r e 14.6 Member end moments, shears, and axial forces.
APA Research Report 151, Plywood End Shear Walls in Mobile Homes , covered mono-
tonic tests conducted on several walls with large openings. Most of the wall assemblies
were fabricated using a combination of glue and mechanical fasteners. The report noted
that for shear walls not using glue, analysis as fully composite sections would be inap-
propriate. A computer program was used to compare the results with one of the test
walls, and to determine if the wall performance could be predicted on the basis of a
mathematical model. The computer program in the appendix of that report modeled
the wall using fully composite sections that were converted to equivalent solid rectan-
gular rigid frame members and imaginary support nodes to simulate the eccentricities
that existed in the test setup. It was suggested that the assignment of the support condi-
tions requires a trial-and-error process. The test results showed that the design shear
load for most walls is controlled by strength, not deflection. The wall deflections calcu-
lated by the computer program were in good agreement with the test results for the
wall being compared. This approach is similar to the method outlined above. An exam-
ple of a computer output of the results can be seen in Fig. 14.6. The member end forces
are shown for reference only.
