“…Çalışmaları neticesinde, zemin-yapı etkileşimi modelinin, zemini rijit kabul eden yaklaşımdan farklı olduğunu, etkileşimli modelde periyotların, gerilmelerin, iç kuvvetlerin zemin özelliklerine göre değiştiğini, yapı periyodunun rijit zeminli modele göre daha yüksek olduğunu ve etkileşimin yapıya etkiyen deprem kuvvetini değiştirdiğini ifade etmiştir. Anderson, Carey ve Amin (2011), büyük ölçekli ağır sanayi yapılarının varlığının yapı-zemin etkileşimi kapsamında yakın civardaki diğer binalar üzerinde oluşturacağı etkileri incelemişlerdir. Çalışmaları sonucu, yapı-zemin etkileşiminin varlığına bağlı olarak çevre yapıların bazılarının yapısal tepkilerinde artış meydana geldiğini belirtmişlerdir.…”

Türkiye, bulunduğu coğrafyada ki aktif faylar sebebiyle sıklıkla büyük depremler ile yüzleşmekte, can kayıpları yaşanmakta ve maddi hasarlar oluşmaktadır. Bu bakımdan yapı tasarımında, deprem kuvvetini etkileyebilecek tüm parametrelerin göz önünde bulundurulması ve hesaplamalara dahil edilmesi oldukça önemlidir. Bu çalışmada, kazıklı temel sistemine sahip betonarme bir yapı ile temel zemini arasındaki etkileşim incelenmiştir. Zemin-kazık-yapı etkileşimi, altsistem yaklaşımı “Yöntem I” ile hesaplamalara yansıtılmış olup üstyapı, temel ve kazıklarda iç kuvvet, yer değiştirme ve şekil değiştirme talepleri elde edilmiştir. Sonuçları mukayese edebilmek için aynı yapı, kazıklara tanımlanan yatay yatak katsayısı yayları ile tasarım spektrumu etkisinde analiz edilmiş ve son olarak ise etkileşimsiz durumda ki sonuçlar için yine aynı yapı zemine ankastre mesnetli şekilde modellenerek hesaplama yapılmıştır. Her üç yöntemden elde edilen sonuçlar mukayese edilerek zemin-kazık-yapı etkileşimi irdelenmiştir.

“…In view of the structural characteristics of NPPs, the structural dimensions and weights of different functions will vary greatly. In terms of research on interaction between adjacent structures with different weights and sizes, Naserkhaki et al [10] and Anderson et al [11] found that relatively light structures have very small interaction effects on heavier structures, but heavier structures have very significant effects on lighter structures. In addition, Roy et al [12] studied the dynamic response of adjacent surface structures under different soil conditions, foundation burial depth and structure spacing, mainly considering the influence of structure weight on system response spectrum and peak acceleration.…”

After the Fukushima nuclear accident in Japan, whether the structural safety of the nuclear power plant (NPP) can be guaranteed under an earthquake has been of wide concern. Automatic seismic trip systems (ASTS) have been deployed in NPPs. There are generally two units or more double units on the one NPP site, and the vibration energy of the structure can certainly affect its adjacent structures through the soil, and there is energy transfer and conversion between adjacent structures. At present, the distance between two reactors of NPPs of different reactor types is generally 100–200 m (this distance is referring to the distance between the centers of two reactors, which is slightly different for different reactor types). In the past, seismic instruments were used in the ASTS and the setting of shutdown threshold, so the impact of only one unit was considered in the structural analysis of NPPs, and the interaction of two reactors through site conditions was not considered. In addition, as the site conditions of NPPs become more and more complex, it is necessary to consider the impact of one reactor structure on another reactor structure through the soil on the same site under an earthquake. In order to analyze the influence of structure–soil–structure interaction (SSSI), a three-dimensional refined finite element model of NPPs is established in this paper. The soil–structure interaction (SSI) is considered by using viscoelastic boundary. The seismic responses of different positions of the raft foundation and NPP structure, under the conditions of considering SSI effect (one reactor) and SSSI effect (two reactors), are compared. The influence of SSSI effect on the seismic responses of the raft foundation and NPP structure is revealed. It is proposed that SSSI effect should be reasonably considered according to the site conditions for the structural analysis of NPPs for the NPP ASTS.

“…The rapid progress of SSSI studies in subsequent decades has been stimulated by the needs of nuclear power plants (NPPs), which always consist of a reactor building adjacent to a turbine building and control building [21][22][23] . In recent years, apart from its continuation in NPPs [24][25][26][27] , studies related to the SSSI have focused more on structure clusters in urban areas. Population growth and the limited available urban space in large cities, such as New York, Istanbul, and Shanghai, inevitably result in the closer spatial proximity (only a few meters or even a few decimeters) of structures, which has even caused the occurrence of seismic pounding of adjacent structures [28,29] .…”
