Outline of Final Research Achievements

We studied and proposed about wooden shear wall with aluminum alloy dampers. Based on the simulation result, the static cyclic loading test on the connection was conducted to examine the mechanical performance of the connection. And, from the performance test of the bearing wall with the proposed aluminum dampers, assumed performance was not obtained because of the plasticity at the connection point between aluminum dampers and wooden surface. And, we developed the other system with steel dampers. The seismic device which consists of mechanical linkage and steel dampers has been proposed to prevent wooden houses from soft-story mechanisms under severe seismic excitation.
