Bu çalışmada, elastik zemine oturan, enine kuvvet ve momentlere maruz bir kirişin dinamik analizi incelenmiştir. Temel modelinde Winkler hipotezi baz alınmıştır. Kiriş üzerindeki tekil etkiler, diferansiyel denklemi kullanabilmek amacıyla, Dirac dağılım teorisi vasıtasıyla yayılı yüklere dönüştürülmüştür. Çalışmanın kullanışını göstermek amacıyla açıklayıcı bir örnek sunulmuş ve bir kısım hesaplanan değerler tablolarda ve şekillerde verilmiştir.

DYNAMIC ANALYSIS OF FOUNDATION BEAMS SUBJECTED TO TRANSVERSE LOADING ON WINKLER SOIL

Öz

In this study, the dynamic analysis of a free beam subjected to transverse forces and moments on an elastic soil are investigated. The foundation model is based on the Winkler hypothesis. Concentrated disturbances on beams are transformed to distributed loads in order to be able to use the governing differential equation established for distributed loads by using Dirac distribution theory. An illustrative example is presented in order to demonstrate the use of the study and some of the obtained results are given in tables and figures.
