How to cut the real accelerogram earthquake record at some time interval to ensure that the maximum effect of the complete earthquake record is achieved by cutting the record up to some extent?
Is there any criteria or guideline to cut the record based on... i.e. Ground motion intensity, Energy etc.. Or any other ?
My FE model is very large and need to perform the seismic analysis using cutted earthquake record.
Dear Mr. Muhammad Farhan,
First of all you must get Fourier Spectra from your real accelerogram and understand how close is the value of the predominant period of your earthquake record to the value of the vibration period of your building under consideration.
Then it will be easy to understand which part of the selected accelerogram you must keep for your analysis and which part you can cut/disregard. Applying the part of accelerogram that gives you predominant period closest to the vibration period of your building will give the best results.
