2020年10月30日，土耳其和希腊爱琴海沿岸发生6.9级地震。震中位于萨摩斯岛阿夫拉基亚定居点东北约14公里处，土耳其伊兹密尔镇塞费里希萨尔西南约25公里处。地震造成的破坏主要集中在伊兹密尔市某些地区的中层钢筋混凝土建筑。在受该活动影响的各种建筑类型中，有土耳其和希腊常见的传统/乡土混合木材-砖石和砖石建筑。本文根据英国结构工程师学会（IStructE）的地震工程现场调查小组（EEFIT）在两国受灾地区进行的广泛的现场和远程侦察调查，总结并讨论了在这些类型的建筑物中观察到的破坏水平和机制。然后根据维修水平和占用状况讨论观察到的损坏情况。收集的数据还用于经验性地构建脆弱性曲线，以评估是否可以使用小样本来描述该地区建筑物的整体性能，以及如何将这些结果与先前对可比建筑存量的研究结果进行比较。
On 30th October 2020, an earthquake of magnitude 6.9 hit the Aegean coasts of Turkey and Greece. The epicentre was some 14 km northeast of Avlakia settlement on Samos Island, and 25 km southwest of Turkish town Seferihisar, Izmir. The destruction the earthquake caused concentrated mainly on the mid-rise RC buildings in certain districts of Izmir city. Among the diverse building typologies affected by the event are the traditional/vernacular hybrid timber-masonry and masonry buildings that are common to Turkey and Greece. This paper summarises and discusses the damage levels and mechanisms observed in these types of buildings, based on an extensive field and remote reconnaissance survey in the affected areas in both countries conducted by the Earthquake Engineering Field Investigation Team (EEFIT) of the United Kingdom Institute of Structural Engineers (IStructE). The observed damage is then discussed in light of the level of maintenance and occupancy status. The collected data are also used to empirically construct fragility curves, to assess whether a small sample can be used to describe the overall performance of the buildings in the area and how these compare to the outcomes of previous studies on comparable building stocks.
