Sažetak
On November 26, 2019, a magnitude Mw = 6.4 earthquake struck Northwestern Albania. It was the strongest to hit Albania in more than 40 years. Cities such as Thumanë, Tirana, and Durrës suffered damage, but Durrës was the hardest hit with several building collapsed [1, 2]. A reconnaissance team under the auspices of American Concrete Institute (ACI) visited Durrës, Albania to assess the extent of damage to modern reinforced concrete (RC) buildings (i.e. built after 1990). The team*1 surveyed buildings during the week of January 12, 2020, with a focus on RC buildings that were infilled with clay block masonry. Over the course of seven days the team documented 55 buildings that had RC frames as their main lateral resisting system. All of the surveyed buildings had unreinforced masonry infills (hollow clay blocks). Most of the buildings had ribbed or waffle slabs. Typical damage observed in these buildings was in- plane or out-of-plane failure (dominant) of masonry infill walls throughout the building height. More damage was observed when these masonry walls were not confined well within the RC frame i.e. acting as partitions. In many cases, these masonry walls were not connected to the RC frame at all, having only bed- joints filled with mortar. This report focuses on the performance of masonry components (infill walls, partitions, etc.) in the buildings in Durrës that were affected by the earthquake. Examples of the damage to the masonry infill, structural details that affected the damage, and its impact on building performance are described. The paper provides an overview of the earthquake- induced damages in several building types and their variation within different structural systems focusing on RC frames with unreinforced masonry infills in Durrës. Reasons for significant differences in observed damage will be discussed in close relation to the building code development and the preferred design concepts. Besides response phenomena and typical damage patterns which have been observed after other earthquakes worldwide, an attempt is made to investigate parameters with high damage potential according to [3].
