چکیده مقاله
Most recent seismic codes include response modification factor in the definition of equivalent lateral forces to reduce the linear elastic design spectrum to account for energy dissipation capacity of structure In this paper, application of Endurance Time ET method in nonlinear seismic analysis has been investigated A set of three acceleration functions have been applied to various steel moment resisting frames and derived results are compared to Incremental Dynamic Analysis IDA results ET analysis results accuracy in evaluation of response modification factors has been assessed according to frames performances evaluation and compared to IDA accuracy in this regards It is observed that the response modification factors resulted from ET analysis are compatible with those obtained from IDA in most cases Considering the great amount of computational efforts that should be done for evaluating response modification factors by IDA, ET analysis can reasonably evaluate them with less analysis
