  • Aimed at physical and geometrical uncertainties broadly existed in practical engineering, an effective method for the supremum and infimum of the static response of structures with bounded uncertainties was presented. The linear interval equations were changed into two standard linear programming problems, and the mathematical proof was given. By the interface program with the finite element analysis(FEA) software ANSYS and the interval computation program, the method was extended to the practical engineering area. The static response intervals were estimated by taken example for a long-span steel framing building. The results show that this method can not only give the result as exact as the traditional Deif-s method, but also have the less calculation times. The interface program with the FEA software ANSYS and the interval computational program can be used for solving the problems of practical engineering structures, directly.
