In this study, internal force influence surface coefficients of plates resting on Pasternak foundation are obtained using the finite element method applying the classical Müller-Breslau Principle. The two-parameter elastic foundation is represented by the inclusion of the elastic bedding and shear parameter matrix terms of a 4-noded soil finite element to the corresponding stiffness matrix terms of the plate finite element used in the implementation. The loading matrices used to determine the influence surfaces directly are derived from the governing equations and the element matrices which are obtained using the Betti’s law. Internal force influence surface coefficients of plates with and without elastic foundation are given comparatively through numerical examples, confirming the values with another approach and the literature.

Bu çalışmada, Pasternak tipi zemine oturan plakların iç kuvvet tesir yüzey katsayıları sonlu elemanlar yöntemiyle klasik Müller-Breslau Prensibi uygulanarak elde edilmiştir. İki parametreli elastik zemin, 4 düğüm noktalı bir zemin sonlu elemanın elastik yataklanma ve kayma parametresi matris terimlerinin, kullanılan plak sonlu elemanın ilgili rijitlik matris terimlerine eklenmesiyle temsil edilmiştir. Tesir yüzeylerini doğrudan belirlemek için kullanılan yükleme matrisleri, ana denklemlerden ve Betti yasası kullanılarak elde edilen eleman matrislerinden türetilmiştir. Elastik zemine oturan ve zeminsiz plakların iç kuvvet tesir yüzey katsayıları, sayısal örneklerle karşılaştırmalı olarak verilmiş, elde edilen değerler başka bir yaklaşımla ve literatürle doğrulanmıştır.
