YAPILARIN DEPREM RİSKİNİN SOKAK TARAMA YÖNTEMİ İLE BELİRLENMESİ: SİVRİHİSAR ÖRNEĞİ

Abstract

Turkey is located in one of the major earthquake zone, has been exposed to many earthquakes from past to present.Earthquakes have caused big damage in buildings and numerous deaths in Turkey.The increase in the existing building stock day by day and the aging of the buildings risethe risk of damage occuringduring an earthquake.However, earthquake risk assessment of all structures is difficult in terms of both cost and time. Practical methods are needed to determine structural response to earthquakes and their seismic risks.Street screeningis one of these methods to evaluate theseismic risks ina particular region. In this study, it is aimed to determine the earthquake risks by evaluating with streetscreening method the structures located in Sivrihisar district center, the biggest district of Eskişehir.Streets and alleys with dense building stock in the district has been determined, 170 buildings have been examined and speculated aboutearthquake risk. It is determined that the majority of the buildings in the district center are masonry and mixed structures, and 27% of these structures have a high risk of damage in the possible earthquake.In this region, which is under the threat of earthquake, it is recommended to make more detailed investigations in high-risk buildings and to decide whether to strengthen or demolish the building.In addition, the importance of enlarging such studies in earthquake zones is emphasized.
