DEVELOPMENT CASE OF HIGH DAMPING WALL FOR WOODEN DWELLING HOUSE AND EXPERIMENT VERIFICATION OF DAMPING PERFORMANCE

Abstract

The development case of high damping walls with workability, low cost, a small number addition and high damping performance is reported.
The verification experiment of structural damping performance is conducted. And the result is reported as follows. (1) The maximum equivalent damping factor of the walls is 29%. (2) The maximum decreasing ratio of response displacement is 40%, and the ratio of acceleration is 59% in many full scale shaking table tests. (3) The contributory effect of stiffness on the response is cleared. (1) The decreasing ratio 51% of displacement and the 71% of acceleration were the contributory effects of the stiffness.
