タイトル（英）：	VIBRATION PROPERTY IDENTIFICATION OF EXPOSED STEEL COLUMN BASES INSTALLED IN PENDULUM-TYPE EARTHQUAKE RESPONSE OBSERVATORY
抄録（英）：	An observatory termed ‘Steel Swing’ has been developed, where a 15000 kg pendulum is hanged from a stiff steel frame. A building element can be tested after inserted between the pendulum and the frame. Free vibration, forced vibration tests and earthquake monitoring were performed on an exposed box-type steel column base. The response records monitored during natural earthquakes were used to identify the vibration property of the specimen. Identified system gain was approximated by a theoretical gain of linear SDOF system, and the response calculated based on such a linear system agrees with the monitored response fairly well. This research technique can be applied to check the behaviours of new materials and new details of connections, and the safety of non-structural elements as well.
