结构可靠性界限计算的包络面方法
Envelope Surface Method for Computing Structural Reliability Boundary
摘要
Abstract
Structural reliability boundary calculation method is proposed based on the Second order reliability method(SORM) and the envelope surface.Rotating paraboloids were applied as the interior and the exterior envelope surface of the limit state surface in most probable failure region,and the failure probability of envelope surface was calculated to determine the structural reliability boundary.The feasibility and accuracy of this method was verified by two numerical examples.The results obtained by this method agree well with those by the Monte Carlo method,and the relative error of this method is small.关键词
