Abstract :
A detailed analysis of the recorded seismic response of a reinforced concrete building, during the August 30-31, 1986 Romanian earthquake is presented, to detect the changes in the dynamic characteristics of the structure. The approach combines the ARX model identification for a multi-input single-output system, with some known detection schemes from literature, investigated in this special context.
