Newmark Yöntemine Göre Zemin Deplasmanının Tahmin Edilmesi

Deprem kaynaklı meydana gelmesi muhtemel zemin deplasman miktarının tahmin edilmesi hem üstyapılar hem de alt yapılar için önem arz etmektedir. Bu hareketin miktarını tahmin edebilmek için literatürde bazı yöntemler geliştirilmiştir. Bu yöntemlerin en önemlilerinden biri de Newmark Kayan Blok Modeli’dir. Bu yaklaşıma dayalı olarak birçok regresyon formülü üretilmiştir. Öncelikle daha önce ortaya konan bu formüllerin bu çalışmada kullanılan dünya genelindeki deprem verilerine göre yeniden analizi gerçekleştirilmiş ve elde edilen sonuçlar irdelenmiştir. Sonrasında bu makale kapsamında yeni bir regresyon denklemi elde edilmiştir. Regresyon analizlerinin karşılaştırılması sonucunda, yeni formülün standart sapma ve R2 açısından daha uygun sonuçlara sahip olduğu tespit edilmiştir.

Estimation of Ground Displacement According to Newmark Method

Prediction of the amount of possible ground displacement caused by an earthquake is important for both superstructures and infrastructures. In literature, some methods have been developed to estimate the amount of this movement. One of the most important models of these methods is Newmark Sliding Block Model. Many regression formulas have been produced based on this approximation. Primarily, these formulas have been re-analyzed according to world-wide earthquake data used in this study and the results have been examined. Then, a new regression equation has been obtained within the scope of this paper. In consequence of the comparison of the regression analyses, it has been determined that the new formula has more appropriate results in terms of the standart deviation and R2.
