The vulnerability of buildings faces further scrutiny as gaps in design, construction, operation, and maintenance remain. Although there has been noticeable progress in the field, the frequency and magnitude of building damage during natural events highlight the fact that sustainable infrastructure has not yet reached all targets. In this study, sustainability aspects of vulnerable buildings are revisited to propose more robust measures to prevent damage and a lack of functionality. Those measured are underpinned by the merging of environmental and structural sustainability for one novel integrated approach. The method devises structural intervention scenarios based on damage levels and service period. It also aims at reducing resource use and embodied impacts through the discretization of standard life cycle analysis into customized stages. The integrated method to evaluate sustainability is tested on two vulnerable buildings in Turkey and Mexico, built with different codes of practice and having experienced low to medium damage during severe earthquake events. Research findings indicate that although embodied impacts form a minor part of the building life cycle environmental impacts, sustainable structural interventions can further reduce both embodied impacts and demands on natural resources. Hence strengthening vulnerable buildings can provide an advantage to help the sustainable transformation of cities.

“…Based on the geological and geophysical data as well as the field monitoring, Kim et al (2018) concluded that the 2017 Mw 5.4 Pohang earthquake in South Korea was induced by the dynamic disturbance of hydraulic fracturing in the enhanced geothermal system. After analyzing the strong ground motion data recorded by 22 accelerometers during the Van earthquake (Turkey) 2011, Beyhan et al (2019) pointed out that the strongest ground shaking occurred around the location of the large slip asperities. However, previous studies are isolated and segmentary, and no systematic investigation on the dynamic behavior and response of rocks during construction and operation of major engineering projects has been performed.…”

Many large engineering projects, e.g., the Sichuan–Tibet Railway, inevitably cross the earthquake active areas and the geology complicated zones, facing the challenges of dynamic disturbances and disasters. In view of this, the conceptualization of engineering disturbed rock dynamics is proposed in this paper, aiming to systematically study the rock dynamic behavior and response subjected to engineering disturbances, to establish the 3D rock dynamic theory, and to develop the disaster prevention and control technical measures. The classification standards of rock loading states based on strain rate are summarized and analyzed. The engineering disturbed rock dynamics is defined as the theoretical and applied science of rock dynamic behaviors, dynamic responses and their superposition caused by dynamic disturbances during engineering construction and operation periods. To achieve the goals of the proposed engineering disturbed rock dynamics, a combined methodology of theoretical analysis, laboratory experiment, numerical simulation and in situ tests is put forward. The associated research scopes are introduced, i.e., experimental and theoretical study of engineering disturbed rock dynamics, wave propagation, attenuation and superposition in rock masses, rock dynamic response of different loading conditions, dynamic response of engineering projects under construction disturbance and disaster mitigation techniques, and dynamic response of major engineering projects under operation disturbance and safety guarantee measures. Some theoretical, experimental and field preliminary studies were performed, including dynamic behavior of disturbed rock at varied depth and strain rates, dynamic response of rock mass subjected to blasting excavation disturbance and dynamic drilling disturbance, and disturbance of rock mass subjected to TBM excavation. Preliminary results showed that the rock masses are significantly disturbed by dynamic disturbances during construction and operation periods of engineering projects. The innovative conceptualization of engineering disturbed rock dynamics and the expected associated outcomes could facilitate establishing the 3D rock dynamic theory and offering theoretical fundamentals and technical guarantees for safety and reliability of the design, construction and operation of modern large engineering.

Bu çalışmada, sıvılaşma potansiyeli yüksek zayıf zeminlerde anakayadan zemin yüzeyine doğru hareket eden deprem dalgasına etki eden zemin büyütme faktörü araştırılmıştır. Bölgesel jeoloji ve temel zemini şartları, yer hareketinin özelliklerini önemli ölçüde değiştirebilir. Bu nedenle, özellikle yumuşak zeminler için, bir deprem sırasında zemin büyütmesinin belirlenmesi, araştırmacılar için çok önemli bir konudur. Araştırmada Adapazarı ilçesi, Tığcılar mahallesindeki mevcut bir yapının zemin profili kullanılmıştır. Deprem sırasında zeminin derinliklerinden zemin yüzeyine doğru hareket eden deprem dalgasının büyüklüğü değişmektedir. Bu değişim zemin tabakalarının özelliklerine bağlı olarak gerçekleşmektedir. Ana kayadan gelen deprem dalgası zemin tabakalarından geçerek zemin yüzeyinde büyümektedir. FLAC 2D programı yardımı ile kurulan modellerde yapılan analizler sonucu oluşacak düşey ve yatay ivme değişimleri incelenmiştir. Yapılan çalışmanın sonucunda zemin özelliklerinin yer hareketini artırdığı görülmektedir. Zemin büyütme etkisi nedeniyle önerilen tasarım spektrumlarını aşılabileceği görülmektedir. Adapazarı bölgesi gibi yumuşak zeminlere sahip ortamlarda yerel zemin koşullarının dikkate alınması gerekmektedir.
