چکیده:
The conventional Incremental Dynamic Analysis (IDA) -a parametric method- is a collection of time history analyses under ground motion records which is scaled to different intensity levels. This range is selected so that can cover all structural behavior. Finally, the results are illustrated in one or more diagrams known as IDA curves. Based on recent studies, a few alternative methods to gain the IDA curves have been proposed. In this essay, the proposed methods are discussed and compared. Then the comparison and advantageous of different methods are discussed for a moment-resisting frame (MRF) under a certain earthquake record.

چکیده:
Incremental Dynamic Analysis (IDA) is a parametric analysis method that has recently emerged in several different forms to estimate more thoroughly structural performance under seismic load. It involves subjecting a structural model to one or more ground motion records. This method considers both inherent randomness and model uncertainty, so it used to probabilistic analysis of structures at high seismic loading. The objective of this study is to improve efficient, but accurate procedures for probabilistic analysis of nonlinear seismic behavior of structure. According to the three-parameter Log-normal distribution more rationally describe maximum story drift ratio at a higher value of spectral acceleration. The traditional method based on two-parameter Log-normal distribution is compared with the presented procedure based on three-parameter Log-normal distribution on analytical data. Improvement in the probabilistic estimation of maximum story drift ratio demand are illustrate with a SAC-9 story, moment resisting frame building exposed to a set of 20 ground motion.
