{"title":"A Procedure for Post-Earthquake Damage Estimation Based on Detection of High-Frequency Transients","authors":"Aleksandar Zhelyazkov, Daniele Zonta, Helmut Wenzel, Peter Furtner","volume":143,"journal":"International Journal of Structural and Construction Engineering","pagesStart":1135,"pagesEnd":1142,"ISSN":"1307-6892","URL":"https:\/\/publications.waset.org\/pdf\/10009832","abstract":"In the current research structural health
\r\nmonitoring is considered for addressing the critical issue of
\r\npost-earthquake damage detection. A non-standard approach
\r\nfor damage detection via acoustic emission is presented -
\r\nacoustic emissions are monitored in the low frequency range
\r\n(up to 120 Hz). Such emissions are termed high-frequency
\r\ntransients. Further a damage indicator defined as the
\r\nTime-Ratio Damage Indicator is introduced. The indicator
\r\nrelies on time-instance measurements of damage initiation and
\r\ndeformation peaks. Based on the time-instance measurements
\r\na procedure for estimation of the maximum drift ratio is
\r\nproposed. Monitoring data is used from a shaking-table test
\r\nof a full-scale reinforced concrete bridge pier. Damage of the
\r\nexperimental column is successfully detected and the proposed
\r\ndamage indicator is calculated.","references":"[1] M.
