Bu Çalismada çesitli boyutlardaki 4 tarafindan tutulmus(ankastre) plaklarin farkli yüklemeler altindaki maksimum deplasman degerleri için öncelikle sonlu elemanlar yöntemiyle çözüm yapan Sap2000 paket programiyla çözümler yapilmis daha sonra problemin Bulanik Mantik yöntemiyle çözülebilirligi arastirilmis ve bu amaçla Matlab Programinin Fuzzy Toolbox’i kullanilarak problem çözülmüstür. Çözümde Mamdani Yöntemi kullanilmis, plak kalinligi bütün modeller için ayni kabul edilmistir. Uygulamalar da maksimum deplasman plak orta noktasinda olusacagindan plak orta noktasindaki deplasmanlar göz önünde bulundurulmustur

In this study, for the maximum value of the discs of different size and attached from 4 sides. Ander different loadings, initially, solutions was made using Sap2000 packet-program which makes solutions through finit elemets method. Afterwards, the solvability of the problem through fuzzy logic was searched and to this end the problem was solved using the fuzzy toolbox of Matlab Program. In the solution mamdani method was used, disc thickness was accepted the sam efor all the samples. As the maximum displacement would occur at the central point of the disc through the course of the application, the displacements at the central point of the disc were taken into consideration.
