Fuzzy dynamic structural analysis of twodimensional frame with fuzzy coefficients
Abstract eng: In this paper, an approach to dynamic analysis based on the fuzzy set theory is presented as a alternative to the classical stochastic dynamic analysis. The material parameters are considered as fuzzy quantities with a given distribution (fuzzy numbers). The dynamic analysis is then performed with help of the fuzzy arithmetic on α-cuts. The result is in the form of fuzzy numbers. In order to reduce computational time, the response surface function concept is employed. This approach is illustrated in an illustrative example of a 2D frame whose free vibration is analyzed.
