| 摘 要： | 利用地质学中的Kriging方法,建立了结构可靠问题的Kriging模型.利用可靠度计算的方法,对已建立的Kriging近似模型进行了可靠度计算.结果表明:考虑各向异性的Kriging模型精度好于各向同性的Kriging模型;基于Kriging模型的可靠度计算,不仅能明显地减少计算量,而且降低了可靠计算中的非线性,提高了收敛速度.

| Abstract: | The Kriging model of structure reliability problems was formed based on the Kriging method in geology.The reliability index of the approximate Kriging function was calculated,based on the reliability computation methods.It is showed that the anisotropic Kriging model is better than the isotropic one.At the same time,based on the Kriging surrogate model,the calculation workload is decreased,and the nonlinear of the reliability calculation is reduced,so the convergence is improved. |
