Abstract

In equivalent static method for earthquake resistant analysis and desing of structures, which is the simplest codified procedure, equivalent lateral load concept is utilized for determining the required strength and stiffness. Endurance Time (ET) is one of the newly developed analysis method that overcomes many of the limitations of satatic procedure and can be used for a more rational analysis of irregular and nonlinear structures. In this paper, application of ET method in analysis and design of steel frames has been investigated and results have been compared with the static procedure. One to twelve stories frames have been designed according to the static procedure and in the next step, are subjected to the special intensifying accelerograms that are calibrated with the code (standard 2800 of Iran) design spectra. The capability of the developed intensifying accelerograms in differentiating between strong, standard and weak designs is then investigated. Displacements and stresses at various locations in the frames have been calculated and compared to the target value. In general, the results verify acceptable precision and capability of ET method in predicting the static analysis results bye using a time-history based analysis.
