Abstract

Development of sound methods for analysis, construction and retrofit of the structures located in high seism city areas is one of the most effective methods for reduction of losses. In recent years, along with the developments in computational technology and considerable increase of experience and knowledge in the seismic behavior of structures, alternative methods for evaluation and design of earthquake resistant structures have been proposed. Endurance Time is one of these methods, in which seismic resistance of structures is evaluated considering their performance, while subjected to calibrated intensifying accelerograms. In this paper, damage indexes that can be used in evaluation of endurance time for steel frames, have been studied. Application of endurance time linear and nonlinear analysis of these structures is investigated. The concept of endurance time is explained. Sample intensifying acceleration functions and a few popular damage indexes are selected. Steel frames with 3, 7 and 15 stories are designed and linear and nonlinear static and dynamic analyses under predefined accelerograms are performed. Variations of damage indexes as a function of time are calculated. Endurance time, considering these damage indexes, is calculated and the results of nonlinear endurance time analysis of the steel frames using the Open Seas program are explained and discussed.
