Sensitivity Based Analyses by Artificial Earthquake by Measuring Structural Accelerations for Damage Assessment

In the recent years, damage detection of structures has been one of the active research areas in sensitivity analyses. There are various responses to determine the location and extent of damages in structures which one of them is deformations caused by dynamic stimulation of time history. In this research, artificial acceleration mapping, which is used in time history analyses, produced in agreement with earthquake properties by using wavelet functions. The approach which was used for damage detection was sensitivity based damage detection. Joint deformations caused by artificial acceleration mapping in structures were inputs of damage detection problem. In this research to show the capabilities of artificial acceleration mapping, two numerical cases were studied. Results indicated that artificial acceleration mapping not only was efficient in damage detection, it was more accurate than natural acceleration mapping.
