Abstract

The majority of Turkey's geography is at risk of earthquakes. Within the borders of Turkey, including the two major active faults contain the North-Eastern and Eastern Anatolia, earthquake, threatening the safety of life and property. On January 24, 2020, an earthquake of magnitude 6.8 occurred at 8:55 p.m. local time. According to the data obtained from the stations in the region, peak ground acceleration in the east-west direction was measured as 0.292 g from the 2308 coded station in Sivrice. It is thought that the earthquake with a magnitude of Mw 6.8 was developed on the Sivrice-Puturge segment of the Eastern Anatolian Fault, which is a left lateral strike slip fault, and the tear developed in an area of 50-55 km. Aftershocks ranging from 0.8 to 5.1 Mw occurred following the main shock on the Eastern Anatolian Fault. The earthquake caused severe structural damages in Elazig and neighboring provinces. As a result of the field investigations carried out in this study, significant damage levels were observed in the buildings since it did not meet the criteria in the earthquake codes. Within the study's scope, the structural damage cases in reinforced concrete and masonry structures were investigated. Many structural deficiencies and mistakes such as non-ductile details, poor concrete quality, short columns, strong beams–weak columns mechanism, large and heavy overhangs, masonry building damages and inadequate reinforcement arrangements were observed. Requirements of seismic codes are discussed and compared with observed earthquake damage.

2020年1月24日埃拉泽-西夫里策地震后建筑物的损坏评估

土耳其的大部分地区都有发生地震的危险。境内包括土耳其东北部和安纳托利亚东部两大活动断层，地震频繁，威胁着生命财产安全。2020年1月24日，当地时间晚上8点55分发生了6.8级地震。根据区域内台站资料，Sivrice的2308编码台站测得东西方向的地面加速度峰值为0.292 g。认为此次6.8级地震发生在东安纳托利亚断层的Sivrice-Puturge段，该断层为左侧走滑断层，裂缝发育范围为50 ~ 55 km。东安纳托利亚断层主震后发生了0.8到5.1兆瓦的余震。地震对埃拉孜省和邻近省份造成了严重的结构破坏。在本研究中进行的实地调查结果显示，由于建筑物不符合地震规范的标准，因此观察到建筑物的严重损坏程度。在研究范围内，研究了钢筋混凝土和砌体结构的结构损伤情况。观察到许多结构缺陷和错误，如非延性细节，混凝土质量差，短柱，强梁弱柱机制，大而重的悬垂，砌体建筑损坏和配筋不足。讨论了抗震规范的要求，并与实测震害进行了比较。

期刊介绍： The Earthquakes and Structures, An International Journal, focuses on the effects of earthquakes on civil engineering structures. The journal will serve as a powerful repository of technical information and will provide a highimpact publication platform for the global community of researchers in the traditional, as well as emerging, subdisciplines of the broader earthquake engineering field. Specifically, some of the major topics covered by the Journal include: .. characterization of strong ground motions, .. quantification of earthquake demand and structural capacity, .. design of earthquake resistant structures and foundations, .. experimental and computational methods, .. seismic regulations and building codes, .. seismic hazard assessment, .. seismic risk mitigation, .. site effects and soil-structure interaction, .. assessment, repair and strengthening of existing structures, including historic structures and monuments, and .. emerging technologies including passive control technologies, structural monitoring systems, and cyberinfrastructure tools for seismic data management, experimental applications, early warning and response
