چکیده مقاله:
Today, one of the most up-to-date issues in designing structures is their reliability and functional design. In order toobtain reliability, different parameters of the earthquake history are to be considered as probabilistic so that their effectson the reliability of the structure that can be considered. In fact, it is necessary to consider all possible scenarios in theearthquake event in the probability of failure of the structure, which is recorded using natural records, this is essentiallyimpossible. In response to this engineering need, the use of simulated artificial earthquake records is one alternative. Themost important point in using artificial records is the use of a model that can more effectively capture the effectiveparameters in earthquake production in the production history of time. In this case, by obtaining uncertainties regardingthe effective parameters in that model, it is possible to produce an accidental earthquake production. In this study, the useof piano keys was used to be used as an artificial record. To achieve this goal, six pieces of a piano-sounded piano piecethat has an initial landing, up and then secondary landing are selected. Also, to compare the results of 6 records of thenear area with pulse effect and 6 records of the remote area for the second type soil, the PEER site was extracted. Tocompare the records, the response spectrum and their correlation were used. The results showed that the correlationbetween the selected artificial records for the far field of faults is more than near the fault.
