Fuzzy finite element analysis of structures is applied to the problems, uncertain parameters. In this article fuzzy numbers are used for uncertain parameters and fuzzy finite element method is formulated for static analysis using fuzzy analysis. Interval analysis is used to solve the system of linear interval equations and a modified interval search procedure is used to reduce overestimations. For verification of the proposed modified procedure static analysis of a bar structure is treated with fuzzy finite element method.
