The accuracy of ET method in predicting the response of steel frames in nonlinear analysis is investigated by considering a simple set of MDOF steel frames. Elastic-Perfectly-Plastic material model has been assumed. Results computed with ET method are compared with the results of nonlinear response history analyses. It is shown that in most of the frames, estimations of ET analysis for maximum interstory drift ratio are less than nonlinear response history analysis results. The dispersion of the results of nonlinear response history analysis for the frames that experience more nonlinearity is high. The consistency of the base shears obtained by two methods is acceptable.
