| In order to increase the reliahlity accuracy of complex structures,the basic theory and calculation procedure of quasi-pure probabilistic finite element method(QPFEM)are present-ed in this paper on the basis of third moment reliability analytical model.The evaluation for-mulas of three dimensional QPFEM are derived in the case that the randomness occurs eitherin the load,material properties,geometric shape,or a combination of the these. The reliabilityof pure bending standard notched specimen is calculated by the present method and comparedwith one obtained by experiment and normal PFEM,The result shows that the QPFEM hashigher calculation accuracy. |
