Our faculty member, Asst. Prof. Ali Yeşilyurt, as part of a research group, has published a new article in the Engineering Failure Analysis. The study aims to identify optimal intensity measures for probabilistic seismic demand models of single-domed historical masonry buildings. A methodology based on correlation, efficiency, and practicality is presented for selecting intensity measures, with 38 commonly used measures categorized into four types: earthquake-based, structure-based, event-based, and compound-based.
The Elbistan Ulu Mosque, damaged by the 2023 Mw7.8 and Mw7.5 Kahramanmaraş earthquakes, was selected as a case study. Response spectrum analyses on a 3D model of the mosque were conducted, and regression analyses were performed between engineering demand parameters and intensity measures. Spectral acceleration, spectral displacement, and modified Cordova intensity were determined as the most suitable intensity measures. Additionally, fragility curves were developed based on other relevant measures, such as peak ground acceleration and effective design acceleration.
