VIBRATION ANALYSIS OF 2D FRAME WITH FUZZY INPUT PARAMETERS

This paper presents a new method for analyzing the oscillations of frame with Fuzzy parameters. The solution of the fuzzy vibration differential equation is presented clearly. To test the reliability of the algorithm, the author apply the solution of the oscillation differential equation for free vibration analysis of the 3-storey 1-span flat frame structure, taking into account the resistance to the initial conditions of displacement and velocity given in the form of triangular fuzzy numbers in the document [2]-Page 185. The displacement results from the proposed algorithm are compare to the result in document [2]. The research findings are important and should be considered in the design as well as in the reliability assessment of the structures.
