PERFORMANCE EAVLUATION OF A PASSIVE CONTROL DEVICE FOR WOODFRAME HOUSES BASED ON SHAKING-TABLE-TEST

Abstract

A passive control device with viscous energy absorber has been developed to mitigate the earthquakes damage to wooden houses. This paper describes the experimental results conducted for performance evaluation of houses with the control devices based on shaking-table-tests. Five framed specimens with and without the control device have been tested. It was shown that the maximum displacement of the structures with control device has decreased about as much as 1/3 to 1/2 comparing to the structure without the control device.
