Structural system reliability calculation method
InactiveCN110175395AHigh precisionImprove applicabilityDesign optimisation/simulationSpecial data processing applicationsCorrelation coefficientFirst-order reliability method
The present invention relates to a structural system reliability calculation method which comprises the following steps of S01, acquiring all failure modes of a structure system, and calculating a correlation coefficient between every two failure modes based on a first-order reliability method, S02, setting a failure probability critical value 0 and a correlation coefficient boundary value 0, S03,enabling k failure modes of which the failure probability is smaller than the threshold value 0 respectively to form a group, and p failure modes of which the correlation coefficients with any failure mode are lower than the correlation coefficient threshold value 0 respectively to form a group, S04, sequentially selecting the failure modes with risks from high to low from the remaining failure modes as references, searching for all failure modes of which the correlation coefficients are greater than a correlation coefficient boundary value 0, and dividing the remaining failure modes into q groups, and S05, deriving the reliability index of the structure system according to the clustering result obtained in the above steps. The structural system reliability calculation method provided bythe invention has the advantages that the problems of low precision and efficiency in the solution of the reliability of the system structural system consisting of the structural components with the correlation relationship are solved, the efficiency is improved, and the precision is relatively higher.
