Vibration Control Technology of a Main Hall of Traditional Wooden Structure by Horizontal Viscoelastic Damper

Abstract

Vibration control technology of wooden main hall with flexible horizontal diaphragm was successfully developed. Response displacement of the wooden main hall was demonstrated to be reduced by 10% by employed vibration technology device installed in the horizontal plane. This technique was applied to the main hall of Cho-nenji Temple, in Kawasaki. Earthquake monitoring was performed to verify the effectiveness of equipment installed after completion of construction. Three dimensional analysis using a nonlinear frame model was compared with microtremor measurements and seismic records.
