Performance-based assessment of multi-story unreinforced masonry buildings: The case of historical Khatib School in Erzurum, Turkey

Performance-based assessment (PBA) has become a matter of emphasis for multi-story unreinforced masonry (URM) buildings recently. It is however very hard to assess the performance of the multi-story URM buildings because of their complex engineering characteristics and structural performance. The primary goals of this study are to identify the seismic vulnerabilities of the URM buildings and to evaluate their structural performance based on the PBA principles. In this respect, a concept PBA layout is prepared for the URM buildings to describe better the performance assessment. In order to evaluate the structural behavior and seismic risk for the multi-story URM buildings, the study focuses on a case study of Historical Khatib School, which is located in Erzurum, Turkey, and it was assessed using the previously determined layout steps.
