The limit state equation of engineering structure will be divided into safety and failure of structure state. Currently one-dimensional optimization method of reliability analysis and geometric significance are analyzed. Based on structures non-probabilistic reliability, combining cubic interpolation function the limit state surface is fitted best, narrowing the range of structures reliability index, then in the standard space, the shortest distance of the structure reliability analysis is calculated from the origin to the fitted failure surface. The numerical example is given, illustrating the effectiveness and the feasibility of the proposed algorithm
