Abstract

It is extremely important to better understand the behavior of existing buildings against earthquakes, to reduce the damage that may occur in these structures in future earthquakes, and to repair and strengthen them when necessary. Studies on the earthquake behavior of traditional Himis structures, which constitute a large part of the historical urban fabric in Turkey, are not quite enough. So, using existing example types, the purpose of this study is to examine, wooden himis frame Turkish structures according to seismic loads. In this study, the earthquake performance of traditional Turkish himis structures under different earthquake accelerations and the behavior of structures in earthquakes were investigated. Himis structures are also evaluated in terms of their studs types, as well as material details. The buildings were modeled based on the finite element model approach by Sap2000 V22 software, their dynamic characteristics were determined and time history analyses were performed to obtain drift ratio. Furthermore, the seismic demand of the Himis structure types was defined and compared. Finally, to assess seismic risk and damage estimation, a probabilistic assessment was carried out and the fragility curves for each building type were derived.
