AbstractStability analysis of thin plates is one of the most important factors in designing plate sstructures In order to overcome the difficulties of exact solving for partial differentialequations of plate s buckling using numerical method is proposed Finite strip methodsare the most popular methods in plate s analysis One of these methods is Spline F S M that has more efficacies in boundary conditions modeling and it can impose differences instrip s direction Using this method it cloud be imposed different elastic foundations andsupports in any place of the plate This supports cloud have different stiffness in threedirection For modeling these supports we can use elastic springs with normal androtational stiffness In this thesis by using Spline F S M and spring model we presentcomputational program that used to stability analysis of thin plate structures Localbuckling coefficients of orthotropic plates resting on every type of elastic supports areobtained and the results are compared with known solutions This method like anotherfinite strip methods has a good convergence in stability problems Effect of supportsituations different kind and stiffness of supports and dimension of some kind of it onbuckling coefficient has been controlled With these results we can find a better place andkind of supports for high buckling coefficient and having high stability for plates with in plane loading
