چکیده:

In the present paper, nonlinear behavior of mass concrete is simulated based on smeared crack model and combined with Endurance Time (ET) method for analyzing of an arch dam. ET method is a time-history (TH) based dynamic pushover procedure in which special predesigned intensifying acceleration functions are used for analysis of structural systems and estimation of structural responses in various performance levels by just a single analysis. For this purposeDEZ arch dam was selected as case study and the finite element model of dam-reservoirfoundationsystem was excited in three various seismic performance levels. Based on the extracted results from ET and TH analyses, it was found that ET method at equivalent target time gives reasonable responses in comparison with conventional TH method. In addition, ET method can reduce the total time of analyses, meaningfully.
