Abstract: A speedy accurate solution to structural fuzzy finite element equilibrium equations(SFFEEE), by combining the definition of the solution of interval equations with themechanical meaning of the structural finite element equilibrium equations (SFEEE), wasput forward. The fuzzification of the SFFEEE, which is discussed in this paper, originatesfrom that of material property, structural conditions and external loading. Thecomputing quantity of this solution is almost equal to that of the general finite elementmethod (GFEM).
