FRAGILITY FUNCTIONS FOR MINARETS
Abstract eng: Tall and slender structures have distinct features in their dynamic behavior. A very particular group is the minarets. The historical ones are masonry, while the modern minarets are mostly reinforced concrete. As an inseparable element of mosques, they have a strong presence in many countries. Minarets, whether new or old, get damaged during earthquakes as has been demonstrated during many earthquakes in Turkey and elsewhere. Most recent examples have been the 2011, Van and 2014, Gökçeada events. In this study we attempt to develop fragility functions for minarets, which could be used in probabilistic seismic risk analysis at territorial scale. In the derivation of fragility functions, we rely on observational damage data collected for reinforced concrete and masonry minarets after the two aforementioned earthquakes in combination with the results of nonlinear dynamic analyses. Ground motion intensity values the minarets exposed to are obtained from simulated earthquake ground motion. Parameters of the log-normally distributed fragility curves, i.e. median and standard deviation, are calculated using Maximum Likelihood Estimation (MLE) method.
