Response control technique of the central column in timber five-storied pagoda

Abstract

A response control technique of the central column of a timber five storied pagoda was successfully developed. It was demonstrated that response displacement of the central columns?s top would be reduced by 50% by the developed control vibration device installed between the structural frame and the central column. This technique was applied to a newly built timber five storied pagoda in Fukuoka. Earthquake monitoring to verify not only the analysis model but also effectiveness of the installed device has been performed since the construction completion. 3-dimensional analysis utilizing a non-linear frame model was compared with both the microtremor measurement and the two earthquake records.
