By the passive controlled system which absorbs a part of earthquake energy input into a building, seismic loads which structures bear are reduced and the possibility of a structure design to be able to reduce earthquake resistant elements is expected. This paper presents the results of shaking table test for a frame model of steel with the passive controlled system and the results of reproduction analysis of the experiments by earthquake response analysis, for the purpose of validating the interaction effect of the passive controlled system that used a different damping device together and confirming the passive controlled effect that placed damping devices in the lower floor intensively.
This study adopts the friction wall which has displacement dependence and the oil damper which has velocity dependence, as different passive controlled systems. The availability of the passive controlled system to be suggested in this paper is confirmed from the results of shaking table tests and reproduction analysis of experiments.
