RELIABILITY EVALUATION OF STRUCTURAL SYSTEMS BASED ON APPROXIMATE INTEGRAL METHOD WITH NON-UNIFORM DIRECTIONAL VECTOR

    摘要
  • 摘要: 本文提出了一种新的基于非均匀方向向量求解结构系统失效概率的近似积分法,给出了结构系统失效概率的近似积分公式。通过求解具体问题,证明该方法相当有效,适合于多破损模式、非线性安全边界的结构体系可靠性问题。

     

    Abstract: An new approximHNYB200102027ectional vector. The defects of the ordinary approximate integral method are highlighted. A new formula of structural failure probability is presented. Numerical examples indicate that the present method is effective and widely applicable.
