To bridge the gapbetween the construction theories and the actual construction techniques, safety factors are adoptedfor designing the strength loading of structural members. If safety factors are too conservative,the extra building materials necessary will result in high construction cost. Thus, there has been atendency in the construction field to derive a precise buckling load analysis model of member inorder to establish accurate safety factors. A numerical analysis model, using modal analysis toacquire the dynamic function calculated by dynamic parameter to get the buckling load of member, isproposed in this paper. The fixed and simple supports around the circular plate are analyzed by thisproposed method. And then, the Monte Carlo method and the normal distribution method are used forrandom sampling and measuring errors of numerical simulation respectively. The analysis resultsindicated that this proposed method only needs to apply modal parameters of 7 X 7 test points toobtain a theoretical value of buckling load.
