摘要：A new iterative algorithm is presented for seeking the design point in
   the FOSM reliability index analysis. Based on a deeper insight into the
   poor convergence of available iteration schemes, a criterion is
   suggested to detect zigzagging movements of the solutions. A
   modification to the design point predicted by the classical HL-RF method
   is proposed to eliminate excessive zigzagging iterations. The proposed
   method is based on the interpolation techniques. Numerical examples show
   that the present method is capable of alleviating zigzagging movements
   in the iteration history, and more effective in convergence and
   stability of iterations than the classical HL-RF method and the other
   methods in the related references.
