EXPERIMENTAL STUDY ON RESPONSE CONTROL METHOD OF WOODEN HOUSES WITH ROCKING PILLARS

- Vibration experiments using reduced models -

Abstract

Japanese wooden houses often collapse due to the collapse of the first layer by major earthquakes. One method to prevent the collapse of a specific layer is to place rocking pillars in the building. In this study, the effect of response reduction by inserting rocking pillars was confirmed through vibration experiments using a shaking table. When a 2-story model without rocking pillars was subjected to repetitive vibration, the response gradually increased and eventually collapsed, but when rocking pillars were inserted, the response was greatly reduced, which was found to be effective in greatly reducing the likelihood of collapse.
