Static and dynamic loading tests were carried out in 8 types of shear walls of wooden post and beam construction. Comparative analyses of the results proved the followings with regard to "static and dynamic properties" and "influence of cyclic loading". In the all types, the dynamic load exceeded 1.1-1.5 times as much as the static load even in small displacement. Regarding the maximum load, the static and dynamic loads were almost the same in wooden elements, and the dynamic load was larger than the static load in inorganic elements. "δu" of the all types and "δy" of the wooden elements were smaller under the dynamic load than under the static load. The failure type of wooden boards changed from "pull-out of nails" to "mixture of punch-outs" under the dynamic load, and the others had no change in the static and dynamic loads. Through the influence of cyclic load, the maximum load of the static loading test of plywood and inorganic boards decreased at 10%-20% range.
