This paper presents a method of measuring restoring force characteristic of a structure using synchronized accelometers to estimate degree of damage which is caused by an earthquake. The restoring force characteristic is obtained as relation between measured acceleration and displacement which is computed by integration of the measured acceleration. A set of acceleration data for an 11-storied building which has been monitored in 3 years are used. It is shown that the restoring force characteristic can be measured by the present method. Numerical experiments are carried out to examine the sampling rate and the data length that are needed to accurately measure the restoring force characteristics. It is shown that the minimum sampling rate and data length are 200 [Hz] an 16 [bit].
