| Abstract: | According to the geometrical meaning of the reliability index, a new concept-reliability index vector and corresponding computational method are put forward. The analysis and example results show that the reliability index vector can express reliability index as well as measure the correlation coefficient of limit states. A new method given by the reliability index vector can be used to calculate the correlation coefficient of the limit states, which is a one of the difficult puzzle problems for the structural system reliability analysis and application. |

| Keywords: | reliability index reliability index vector failure mode correlation coefficient |
