On 06 February 2023, two strong earthquakes occurred in Kahramanmara & scedil;, T & uuml;rkiye. The first earthquake with a moment magnitude (Mw) of 7.7 and an epicenter in Pazarc & imath;k, was followed by a second earthquake with a moment magnitude of (Mw) 7.6 and an epicenter in Elbistan. These earthquakes have caused catastrophic life and structural loss in ten cities where more than 15 million people permanently live. Concentrating on the epicenter of the second earthquake, Elbistan, this study investigates the main characteristics of the earthquakes and the failure of the reinforced concrete buildings. Acceleration records from both earthquakes were analyzed and site surveys were conducted to evaluate the caused damages. The high number of completely collapsed buildings highlighted the vulnerability of the general old building stock constructed before 2000. Notably, unlike previous earthquakes in T & uuml;rkiye, these earthquakes also affected new buildings constructed according to the recent Turkish Earthquake Code. In that respect, seismic damages seen in these buildings are presented and interpreted in this paper. To validate the observed deficiencies, a damaged building whose construction had just been completed but not yet occupied was both surveyed on site and subjected to non-linear performance analyses. The analysis results demonstrated that the damage distribution and locations in the models closely matched the observed damage after the earthquakes. In addition, the analyses also revealed the effect of brick infill walls on the building's seismic behavior.
Innovative Technologies for the Protection of Historical Structures Against Earthquakes [article]

Cultural heritage buildings are special structures and must be protected from natural disasters preserving at the same time their authenticity. In the seismic areas, one of the building classes that is consistently exposed to seismic risk is the one constituting the architectural heritage of the region. To minimize further destruction under future seismic activity it is necessary to reinforce the existing structures that are more vulnerable. As a consequence, new technological systems are needed, able to provide solution not only to specific structural or architectural problems, but also aiming at improving the global performance of the construction. Similarly, great attention is paid not only to reliability and durability of intervention methods, but also to the possibility to be easily monitored and removed if required, according to the widely shared policy, aiming at the safeguard of existing buildings, in particular in case of historical and monumental works, from inappropriate restoration operations.This study aims to represent innovative technologies and strategies to preserve the cultural heritage structures against earthquake effect. In particular, the application of fibre reinforced polymers and structural control systems are explained. Suitability of the strategies to architectural, historical and structural features and reversibility aspects are evaluated. As a case study the application of these strategies to a historical building in Istanbul is discussed.
