چکیده مقاله
With the advancement of civil engineering in the constructing of intermediate and high rise structures, the growing human need for accurate and distinct analysis of these structures under the lateral load of the earthquake is felt Comparing the analysis methods with each other leads to understanding and achieving the amount of effort made in the structure and predicting its actual behavior due to earthquakes A new linear based interactive method has been presented before Now, in this section, considering the range of 9 to 19 floors of regular steel flexural frame structures in plan and height and analysis under lateral load, two methods of repetition of generalized linear dynamic analysis and time history nonlinear analysis with EL CENTRO, ALTADENA 1 and LACC NORTH 1 earthquakes have been examined and compared To equalize the conditions of both analyzes, in the generalized linear dynamic analysis repetition method, the stiffness reduction is assigned only to the beams and in the time history nonlinear analysis method, only plastic hinge beams are assigned Convergence speed, method accuracy and economic benefits are the based for comparison in the analyzes The results indicated that all models have converged, and the accuracy of this method was reported to be higher in pulse like earthquakes compared to other types of earthquakes
