This research presents a method based on impulse response to determine the time and location of
plastic hinge formation by using the recorded responses of the structure in time domain without using
complicated transformations. At early stages of earthquake loading, structural systems remain in the elastic
phase but when the loading increases, plastic hinges will be formed and will affect the structural response.
Determining the location and time of this damage can be very important in decision making process. Most of
the previously presented methods aimed at finding the time and location of hinge formation by changing the
response space by employing Fourier, Short time Fourier or wavelet transform methods using changes in
vibration properties of the system like vibration frequency or vibration modes of the structure. But these
methods are not very effective in early warning applications since the vibration properties do not change
significantly at the beginning of plastic hinge formation. The obtained results indicate that the proposed method
can effectively determine time and location of damage without employing complicated methods and concepts.
Key words: Damage detection, impulse response, plastic hinge, shear frame, , ,
