Abstract
The importance of usage of
pile foundation is increasing in soil mechanics and geotechnical engineering in
recent years. The pile foundations are used to eliminate inadequacies related
to bearing capacity of soils. In addition, the piles are used for the purposes
such as sheet pile and sealing sheet piles. Piles are usually exposed to normal
forces but sometimes they can be exposed to lateral loads and moments in
horizontal plane. These types of loadings are quite important for engineering
designs related to piles.
In this paper a
three-dimensional model established by using finite element based software
ANSYS program to demonstrate the moment effects on piles. For this purpose,
piles are modelled with different diameters and lengths. The shear stress
occurred on the pile surface and deformation changes of a certain area
investigated by the effect of moment applied on piles with having different
diameters and lengths. Finally, significant rotation was seen on moment loaded
piles and shear stress occurred between pile-soil interface.

Abstract
Zemin
mekaniği ve geoteknik mühendisliğinde kazıklı temellerin kullanımının önemi son
yıllarda artmaktadır. Taşıma gücü zayıf zeminlerde, taşıma gücü ile ilgili
yetersizliği ortadan kaldırmak için tercih edilen kazıklar aynı zamanda
sızdırmazlık perdeleri, zemin tutma perdeleri gibi amaçlar için de
kullanılmaktadır. Kazıklar genelde düşey yönlü kuvvetlere maruz kalırlar fakat
bazen yatay yüklere ve yatay düzlemde momente de maruz kalabilirler. Yükleme
tipleri kazıklarla ilgili davranışın anlaşılması ve buna bağlı olarak mühendislik
tasarımlarının ortaya çıkmasında çok önem arz etmektedir.
Bu
çalışmada sonlu elemanlar yöntemini kullanan ANSYS paket programı vasıtasıyla
kazık üzerinde moment yüklerinin etkisini göstermek amacıyla üç boyutlu bir
model oluşturulmuştur. Bu amaçla, kazıklar farklı çaplarda ve uzunluklarda
modellenmiştir. Kayma gerilmeleri ve kazık üzerindeki belirli bir noktanın
deformasyonları moment etkisi altında, farklı çaplarda ve uzunluklarda
modellenen kazıklar üzerinde incelenmiştir.
