PROBLEM TO BE SOLVED: To heighten the accuracy of solution and judge the quality of accuracy of solution at first sight by taking in a measured value as a contraint condition. SOLUTION: In setting plural nodes on an element of a structure 1, measuring the actual distanceΔx between a pair of nodes N1, N2 on the element in non- operating state, measuring an actual distortionεproduced between the paired nodes N1 and N2 in the operating state by a distortion gauge, and analyzing the stress caused in the structure, taking the element as the finite element model by a finite element method, the displacements of the respective nodes on the finite element model corresponding to the respective nodes N1, N2 of the element are taken to be U1 and U2, and the following equationε=(U1-U2)/Δx is taken as a constraint condition.
