Prediction of Structural Response to Large Earthquakes by Using Recordings From Smaller Earthquakes

by Erdal ?afak, (M.ASCE), U.S Geological Survey, Reston, United States,



Document Type: Proceeding Paper

Part of: Structures Congress XII

Abstract:

The feasibility of predicting structural response to large earthquakes by using recorded responses from collocated smaller earthquakes is investigated. Records from large earthquakes can be approximated as linear combinations of records from smaller earthquakes. Two methods are introduced to predict structural response to a large earthquake by using the recorded response to a smaller earthquake. The accuracy of the methods are tested by applying them to data from a highway overpass.
