Evaluating the damage content of Karbandi using frequency domain analysis (Case Study: Timche Haj-Mohammad-Qoli of Tabriz Historic Bazaar)

In this study, an alternate method to evaluate structural systems, especially those with historical importance has introduced by applying Fourier Transform (FT) the damage ratio of time history outcome in frequency domain. The concept content (DC) regarding mechanical characteristics used material, including plastic strain, failure plane, and ultimate load-bearing capacity, along drift value, record selection criteria, architectural aspects, have employed. Due its valuable aesthetic view, Timche Haj-Mohammad-Qoli Tabriz Historic Bazaar, one traditional covered spaces complicated configuration spatial masonry intersecting arches, selected for further assessment current research program. required experimental samples obtaining properties relevant geometrical measurements prepare numerical model structure obtained. strong ground motions according seismological geological construction site selected. records different durations were merged Damage Content analysis. According outcomes, state due imposed motion at every stage lateral loading from initiation final collapse was traceable. As a straightforward outcome, vulnerability near-field earthquakes is more tangible than that far-field earthquakes. provided methodology could proper use future similar studies evaluating performance structures.
