A great number of reinforced concrete building structures were damaged or collapsed during the earthquake that hit Sivrice district of Elazığ city located in the southwest of the Eastern Anatolia Region of Turkey on January 24, 2020. Magnitude of the earthquake were announced as Mw=6.5 and Mw=6.8 by Kandilli Observatory & Earthquake Research Institute (KOERI) and Earthquake Department of the Disaster and Emergency Management Presidency (AFAD), respectively. More than a thousand of aftershocks with the magnitude of 1.2–5.1 occurred between January and February 2020. The magnitude of the structural damage was relatively high compared with the peak value of recorded ground acceleration (2.85m/s²) at the epicenter (Sivrice district) of the earthquake. It was determined that 584 buildings were demolished, 6845 were severely damaged, 1207 were moderately damaged, 14,389 were slightly damaged and 14,317 were undamaged. Also, there were 235 buildings that required urgent demolition. In this paper, the performance of the reinforced concrete buildings during the Sivrice-Elazığ earthquake is presented along with time-histories of ground motion records and response spectrums. Observed design and construction practices were carefully evaluated and compared with Turkish Earthquake Code. It was seen that the most significant causes of the failures were due to the poor concrete quality, the use of non-ductile detailing, the poor project design and construction quality. According to field inspections of our technical team, it is concluded that performances of the undamaged buildings following earthquakes do not prove that they have adequate seismic safety.

根据土耳其地震规范对 Sivrice-Elazığ 地震（Mw=6.8，2020 年 1 月 24 日）期间钢筋混凝土建筑的性能评估

2020 年 1 月 24 日，土耳其东部安纳托利亚地区西南部埃拉泽市 Sivrice 区发生地震，大量钢筋混凝土建筑结构受损或倒塌。地震震级为米w=6.5和米w=6.8分别由坎迪利天文台和地震研究所 (KOERI) 和灾害与应急管理机构 (AFAD) 地震部提供。2020 年 1 月至 2020 年 1 月至 2 月，共发生 1.2 ～ 5.1 级余震 1000 余次。与记录的地面加速度峰值（2.85米/秒²) 在地震的震中（Sivrice 区）。确定拆除建筑物584座，严重损毁6845座，中度损毁1207座，轻度损毁14389座，未损毁14317座。此外，还有 235 栋建筑物需要紧急拆除。本文介绍了 Sivrice-Elazığ 地震期间钢筋混凝土建筑物的性能以及地震动记录和响应谱的时间历程。对观察到的设计和施工实践进行了仔细评估，并与土耳其地震规范进行了比较。可以看出，失败的最重要原因是由于混凝土质量差、使用非延性细节、项目设计和施工质量差。根据我们技术团队的实地考察，
