摘要
本文从可靠指标β的几何意义和空间转换入手，探讨了非线性相关变量条件下β的改进、简化计算方法。通过实例计算对比，表明了所提方法的正确性。
Starting from the geometrical meaning and space transformation of reliability index β, this paper discusses the improved and simplified calculation of β under the condition of nonlinear and correlated random variables. Numerical examples show that the improved method is accurate.
