| Abstract: | Based on the first-order second-moment method reliability theory,a method of the two-order second-moment method is proposed.The method considers the Taylor series second-order expansion of structural performance function at the design point.Two example is analyzed,The method is suitable for engineering application. |
| Keywords: | reliability index second-order second-moment method non-liner |
