The summational rule in dynamic properties was verified by using the results of static and dynamic tests on 4 single elements of walls and 3 combination walls of those elements. In comparison between the sum of the load on the single wall elements and the load on the combination walls, the following trends were ascertained in any combinations. When the displacement of the walls was small, the sum of the load on the elements was a little higher than the one on the combination walls. As the displacement became larger, it gradually became lower than the combinations. When the displacement became large enough, it went beyond the combinations again, hi the case of the combination wall with gypsum board and brace, the maximum load and the displacement at the maximum load were larger than the sum of the elements, because the gypsum board prevented the buckling of the brace. Moreover, as the characteristics of the Bi-linear models, the dynamic test results of the combination walls was more than the sum of the static test results of the elements. Analyzing the seismic response with the combination walls that were parallel models of the elements, no fixed trend was found and it didn't always tend to be the same as the analysis with the single elements.
