Abstract

It is well known that the difference between dynamic and static behaviors of wooden walls is affected by loading rate. However, there is no overview in previous research. In this study, we carried out the dynamic and static loading tests to a wooden shear wall and its joints to evaluate the dynamic performance. We found out that shear force in the dynamic loading was 1.2-1.4 times larger than the static loading. Furthermore, shear force combining the element tests were consistent with those from test results of shear walls. Assuming the load increase as a viscous force, it can be roughly evaluated from the loading rate and the equivalent viscosity coefficient can be obtained from the element tests. To the end, we confirmed that the viscous force could be used to estimate the load increase by dynamic loading.
