The contour plot of shear stress and the principal stresses of the panel in three test methods were caluculated and discussed. In the diagonal compression test (method A) the stress concentration was observed near the loading and reacting points. This stress concentration became more conspiquous as the framing thickness decreased. In the simple racking test (method B) the stress concentration was most conspiquous and the shear stress distribution showed clearly the sudden discontinuity of stresses at the bolted point just under the loading point. Uniform stress distribution was found in the racking test with hold-down ties wellknown as ASTM type (method C). The load transmission abilities of these three test methods along the edges of the panels were in the order of C>B>A. While the test method C is the most pertinent method to provide the uniform shear in the specimen, the test method A is thought to be useful when used in tests including a great number of specimens such as the outdoor durability as it is very simple and handy to test.
