ab: Summary: The method of approaching nonlinear limit state equation by linear
    limit state equation is effective in improving the accuracy of
    reliability analysis, and the key to this method is how to choose the
    proper linear limit state equation and its amount. In this paper, an
    effective method is given to calculate the sub-linear limit state
    equation. Based on the obtained nonlinear equation, the next expansion
    point and linear limit equation are acquired with optimally iterative
    calculation. The correlation coefficient between two adjacent linear
    equations is used to judge whether the gained sub-linear equation is
    proper or not. Examples show that the accuracy of the presented method
    is preferable.
