Tahribatsız Yöntemler Kullanılarak Trafik Kaynaklı Yer Hareketi Etkisindeki Tarihi Yapıların Stokastik Dinamik Analizi

Bu çalışmada, trafik geçişleri sebebiyle zeminde meydana gelen yatay mikro titreşim yer hareketi etkisi altındaki tarihi bir yığma yapının stokastik dinamik analizlerinin gerçekleştirilmesi amaçlanmaktadır. Bu amaçla, yerinde tahribatsız yöntemler uygulanarak yapıda kullanılan malzeme özelliklileri tespit edilmeye çalışılmıştır. Yerinde tahribatsız yöntem olarak ultrasonik hız testi uygulanmış ve taş duvar, tuğla kemer ve taş kolonlar için belirlenen noktalardan ölçümler alınmıştır. Yerinde yapılan ölçümler ile elde edilen veriler kullanılarak yapı analizlerinde kullanılan taş kolon, taş duvar ve tuğla kemer için malzeme özellikleri tespit edilmiştir. Bu çalışmada, yapının trafik etkisi altındaki stokastik dinamik analizlerinin elde edilmesi için trafik kaynaklı yer hareketi modeli elde edilmiştir. Stokastik dinamik analizler yapının hasarsız (çatlaksız) ve hasarlı (çatlaklı) halleri için gerçekleştirilmiş ve sonuçlar karşılaştırılmıştır.

Anahtar Kelimeler:

Çatlak, stokastik dinamik analiz, ultasonik hız testi, tahribatsız test, tarihi yığma yapı

Stochastic Dynamic Analysis of Historical Structures subjected to Traffic-induced Ground Motion using Non-destructive Methods

In this study, it is aimed to perform stochastic dynamic analysis of a historical masonry structure subjected to horizontal micro vibration ground motion occurring on the ground due to traffic transitions. For this purpose, non-destructive methods were applied to determine the material properties used in the historic building. Ultrasonic velocity test was applied as a non-destructive method and measurements were taken from the points determined for stone walls, brick arches and stone columns. The material properties of the stone columns, stone walls and brick arches used in the structural analyzes were determined by using the data obtained from the on-site measurements. In this study, to obtain the stochastic dynamic analysis of the structure under the influence of traffic, a traffic induced ground motion model was obtained. The stochastic dynamic analysis was performed for undamaged (non-cracked) and damaged (cracked) structure and the results were compared.

Keywords:

Crack, stochastic dynamic analysis, non-destructive testing, historical masonry structure, ultrasonic speed test,
