The seismic response assessment of rocking systems via Incremental Dynamic Analysis (IDA) is investigated, focusing on the issues that arise in analysis and postprocessing stages. Rocking IDA curves generally differ from those hysteretic structural due to (i) frequent appearance resurrections; (ii) their highly weaving non-monotonic behavior; (iii) overall high variability. Hence, including or ...

In this study, an existing hospital structure has been evaluated with incremental dynamic analysis (IDA). This building is accommodated in Karaj with soil type II. At first, two 2-D frames along X, Y direction are selected. Then, five performance levels are determined according to “Rehabilitation Code for Existing Buildings (Publication No. 360) including Immediate Operational (IO), Limited Dam...

This paper proposes an innovative method for determining the approximate incremental dynamic analysis curves of semi-isolated bridges, including derivation statistical mathematical formulas. Ultimately, is devised based on primary and limit state tangential stiffness values bridges. The bridges selected this study are two reinforced concrete highway in United States, which have been optimally r...

In this study a numerical calibration of the most widely accepted damage indices, for quantifying the extent of damage in reinforced concrete structures, is performed. In particular, the Park and Ang local damage index, its modified variant proposed by Kunnath, Reinhorn and Lobo; the Chung, Meyer and Shinozuka local damage index; along with the maximum and final softening damage indices propose...

Incremental dynamic analysis (IDA) requires the analysis of the non-linear response history of a structure for an ensemble of ground motions, each scaled to multiple levels of intensity and selected to cover the entire range of structural response. Recognizing that IDA of practical structures is computationally demanding, an approximate procedure based on the reduction of the number of ground m...
